Moments I love from Digimon Adventure (1999) - [6/?]

🕺🎤 K a r a o k e N i g h t ! 🎤💃

Kaze NO FRAIDOOO POTATOOOO ♫

Because after so much development and traumatic moments, I enjoy some pure joy and fun. Who would have thought that the trio of Taichi, Joe and Mimi would be the funniest. Or that an enjoyable episode like this features the creatures that are Gekomons (I say that because holy shit have you seen those tongues? They have holes, that's some trypophobic nightmare)

Also for some reason Palmon is sleeping very comfortable with Taichi

Special mention to the Koshiro episode because that was a trip, and without realizing you'll be crying because Babumon tears all of the sudden (also Takahiro Sakurai is god so every episode with him on it is nice)

♡ HAIKYUU MEN ASKING TO PUT JUST THE TIP IN ♡

He knows what he is asking for, and just follows his own words. He loves driving you crazy, and gets off mostly by the fact that he knows putting just the tip in us not close enough to satisfy you, and seeing you writhing in frustration makes his feel powerful enough to just get on with it. He carefully never lets more than the tip penetrate your cunt, no matter if you ask or beg him for more. The power play in having your wrapped around the tip of his cock is just the beginning to see you unfold under his ministrations. He wants you to try and grasp his entire length just to let it disappear before your eyes, fully knowing how much you like taking his cock, and enjoying the slow torture he is imposing on both of you.

Daichi, Aran, Iwaizumi, Yamaguchi, OSAMU, Ginjima, Yaku, KENMA, Matsukawa, Komori, Futakuchi, Keishin, Akiteru, Shirabu.

He wants you so bad, that he would be happy about putting the tip in. But it’s not enough, it’s never enough. He tries to control himself, sliding in and out of your wet hole slowly, enjoying the friction between his swollen cock and the tight walls of your cunt, feeling it entering and then smacking out. He tries to keep himself busy in order not to behave like a cave man and fuck you rough, so he sucks your nipples dry, plays with your neck and your lobes, kisses you down to your stomach. His hips circle letting you wholly feel what you are doing to him, until he finally cums and bottoms out in you, and sees you cumming right with him, out of frustration and that slow build up made of heaven promises, and yet still craving for more.

SEMI, Kita, Tendō, Akaashi, Bokuto, H I N A T A, Kyoutani, Oikawa, Hanamaki, Sugawara, Aone, TAICHI, Lev, Hoshiumi, Asahi.

Just the tip? He does not know what ‘just the tip’ means. He drills you with his cock, right from the start, letting his balls slap you, and keeping an insane abs rough pace - disregarding entirely the tip thing. He loves seeing your gasp for air, when the bed has been banging to the wall and your cunt is so full of him, him and his damn huge cock. He just cannot understand how it might be enough not to see you whining and moaning, taking his cock so well, swallowing his length up, and finding that sweet spot inside of you, just to get you to clench your walls tighter around him. His rough fucking brings you to orgasm so hard, you crash right after, as he does, and then only after letting him keep the damn tip in, cockwarming him.

DAISHOU, Ushijima, TERUSHIMA, K U R O O, Atsumu, Kageyama, SAKUSA, Tsukishima, Ennoshita, S U N A, Hirugami.

Takari Headcanons Part II

So here I come with my next Takari Headcanons. Once again I must remind you that these HC applied mainly into the context of my Universer, but some might be valid for the general series.

Let's get to it then!

🌷 🌷 🌷 🌷 🌷 🌷 🌷

🌷 Takeru is a romantic fool due to his literary influences. He's the one who comes with the best date, proposal, confession...ideas, but in real life he's a little cynic about love due to the bad reference/ trauma he got from his parents' breakup. Due to this, he has never taken the idea of "dating" seriously, which is why he can easily go out on dates with girls he has no interests with. With Hikari the situation is different, since he denial originally mistakes his infatuation with Hikari as Pure Friendship interest.

🌷 Hikari is the first one to realize she has feelings for Takeru very early in their friendship. At first she choses to stay quiet believing that the feelings are onesided, but as time passes she figures that it is actually mutual and that Takeru's cynicism is to blame for his apparent denial of it. Instead of pushing the matter and confessing straight away, she teases him and often does things to ruffle his feelings in hopes that he will, once for all, fall into elightenment of his own feelings. The things she often does is commenting on his misadventures with random girls or some friendly flirting with Daisuke (sorry dude) or Shun who supports the cause of making Takeru aware of his feelings.

🌷 Infact, Taichi is the first one to suspect that Hikari has a thing for a boy (Brother's instinct!), but he originally thought that Hikari was crushing on Yamato, it is not until later that he figures that Takeru might be an candidate. Eventually he dismisses the whole thing. Ironically, he's the last one to find out that Hikari and Takeru were in a relationship

🌷 Takeru finally comes to terms with his feelings thanks to a pep talk from Taichi. Ironically, the pep talk came after Taichi was venting over his soccer team members (yeah he still plays in college) were trying to hit on his little sister.

🌷 Hikari seems to be magnet for soccer players lol

🌷Taichi actually approves of the relationship, but he likes to tease Takeru making him think that he will kill him if he does anything improper to his sister. Yamato is delighted with the news.

🌷 Mimi (and by default Koushiro) is the first to find out about the relationship after she casually caught them snogging during one of their secret dates. She eventually uses this to blackmail them to stay quiet about her own love life.

🍀 In my verse, Hikari's birthday falls on November 11th. I chose this date because based on months and personalities, November children are psychic, empathic and positive, but easily overwhelemed by the sensitivity which often causes them emotional burden. 11th, because using numerology, people born on the 11th day are usually very aware of their surroundings, intuitive and supportive; but they are also very secretive. This seem to suit her well

🍀 Takeru's birth day is on December 13th. December childre are loyal, generous, pretty boys and girls that are easily loved and admired, very active, outspoken and influential. Then can be very impatient but are always willing to give and help. People born on the 13th day are very hardworking, creative and optimistic.

🍀 Takeru introduces Hikari into the literature world and turns her into an avid reader. They reach a point that they use a secret code consisting of fictional language words, author names and quotes to pass messages between each other. No one understands them and wonder why they can't simply flirt like normal people.

🍀 At last year of college, Takeru receives a scholarship to take postgraduate studies in England (a writer's dream lol), so he has to go overseas. Hikari often goes to visit during vacations.

🍀 Takeru is pride boyfriend who always talks about his grilfriend, so the whole literature department already knows about Hikari before she is even introduced to them. She has earned the "MUse" nickname between them

🍀 Takeru proposes during "by accident" at some point during this time. He had been jugling with the idea for a while and during a field trip to Ireland he ends up buying the engagement ring in a celtic store. He gets a Claddagh ring with Topaz (Hikari's birthstone) and Turquoise (Takeru's birthstone) out of impulse, without even realizing what he had done

🍀 Taichi gave him a call and long pep, big brother talk after Hikari dropped the news. Takeru was absolutely terrified. Eventually Taichi is pulled off the phone by Sora, since everyone was impatient to give the congratulations

🍀🍀🍀🍀🍀🍀 This is it for the time being. Don't worry I still have lots of HC if you guys are interested lol ❤ but writing them all down in one single post would sure make a long post. So for now....

TO BE CONTINUED

If you enjoyed this and wanted to share more HC, we have a discord server! Just DM and we can talk about it!!

Isn’t SmI3 an antiferromagnetic Kitaev spin liquid candidate?

“GdV6Sn6 : A Multi-carrier Metal with Non-magnetic 3d-electron Kagome Bands and 4f-electron Magnetism”

H. Ishikawa, T. Yajima, M. Kawamura, H. Mitamura, K. Kindo

Journal of the Physical Society of Japan,  90, 124704 (2021).

GdV6Sn6 is a layered stannide where V-kagome lattice and Gd-triangular lattice coexist. While unconventional magnetotransport is expected by the interplay between the band structure inherent to the kagome lattice and frustrated magnetism, its physical properties are not investigated  since the discovery in 2011 (L. Romaka et al. J. Alloys Compd. 509, 8862, 2011). We have synthesized high quality single crystals and investigated its physical properties by resistivity measurements up to high magnetic fields and the first principles calculations.

“Phase transition in the 5d1 double perovskite Ba2CaReO6 induced by high magnetic field”

H. Ishikawa, D. Hirai, A. Ikeda, M. Gen, T. Yajima, A. Matsuo, Y. H. Matsuda, Z. Hiroi, K. Kindo

Physical Review B, 104, 174422 (2021).

We discovered a novel magnetic field induced phase transition at 50 T in the spin-orbital entangled magnet Ba2CaReO6 with Jeff = 3/2 state. We demonstrate that magnetic properties of the Jeff = 3/2 magnets can be drastically changed by magnetic field as well as by cation or anion substitutions.

“Pressure-induced phase transition in the J1 − J2 square lattice antiferromagnet RbMoOPO4Cl”

“Ligand dependent magnetism of the  Jeff = 3/2 Mott insulator Cs2MX6 (M = Ta, Nb, X = Br, Cl)”

H. Ishikawa, T. Yajima, A. Matsuo, K. Kindo

Journal of Physics.: Condensed Matter, 33 125802  (2021).

The magnetism of the  d1 ion system with strong spin-orbit coupling is systematically investigated. We found that the magnetism is strongly affected by the type of ligand anions, of which roles are often overlooked.

“Nonmagnetic ground states and a possible quadrupolar phase in 4d and 5d lacunar spinel selenides GaM4Se8 (M = Nb, Ta)”

H. Ishikawa, T. Yajima, A. Matsuo, Y. Ihara, K. Kindo

Physical Review Letters, 124, 227202 (2020).

The ground state of lacunar spinel type molecular magnets with 4d and 5d electrons are investigated. We identified non-magnetic ground states and a novel intermediate phase in GaNb4Se8.

“Kitaev Spin Liquid Candidate OsxCl3 Comprised of Honeycomb Nano-Domains”

La2IRu2 crystallizes in the Gd2IFe2-type that is known as “Intermediates between Cluster Compounds and Intermetallic Phases” (M. Ruck and A. Simon, ZAAC, 619 1993). We discovered superconductivity below 4.8 K with high upper critical field preceded by successive phase transitions at 140 K and 80 K. We discuss its properties based on experimental results and first-principles calculations that revealed uncommon formal valences La1.5+, I-, and Ru-.

Inorganic Chemistry, 58, 11949 (2019).

Volborthite is a curious quasi-2D quantum spin system which was first investigated as a distorted kagome antiferromagnet. It is now regarded as a spin system made of coupled trimers and a candidate for realizing the magnetic field induced spin nematic state near the 1/3 plateau state. The up to date experimental results are summarized in this review article.

Large and high-quality single crystal of a distorted spin-1/2 kagome lattice antiferromagnet volborthite were synthesized, which enabled detailed magnetic characterizations. We have observed successive magnetic field induced phases including the 1/3 magnetization plateau and a phase without clear magnetic order. A possibility of the realization of spin nematic state is proposed.

Journal of the Physical Society of Japan, 83, 043703 (2014).

Peculiar MnF7 pentagonal bipyramids in NaBa2Mn3F11 constitute a unique frustrated spin lattice that we named “Kagome-Triangular lattice”. Depending on the relative magnitude of nearest-neighbor interaction J1 and next nearest neighbor interaction J2, kagome lattice (J1 >> J2), triangular lattice (J1 = J2), and triangular clusters (J1J2) are realized. We revealed basic magnetic properties based on bulk magnetic measurement and discuss a possible magnetic order. Incommensurately modulated magnetic structure and zero-energy excitation are revealed by subsequent neutron scattering experiments by S. Hayashida.
