Extended version YT link: 【手描きプロセカ】 月曜日の憂鬱 (Monday's Melancholy) 【司類司】
About Monday’s Melancholy with Tsukasa and Rui. It’s about their first official meeting on kamikou’s rooftop. That’s why they’re wearing indoor slippers. and the drone in the title ahaha
The second half, it progresses from events… mainstory -> kamifes -> wms -> dazzling light. Other than it going by events, the colour also goes from orange/yellow (Tsukasa) -> pink (Emu) -> green (Nene) -> purple (Rui). The order of who officially joined the group.
A little something Rui’s Phenoix Wonderland’s ticket hm
