Introducing my magical girl OC Flora! She is the adoptive daughter of the Marvelous Quartet and eventually gains magical girl powers and joins their team (officially becoming the Marvelous Quintet). Flora was born to the same top-secret project that Iris was, but because of certain events was allowed to be raised by the Quartet and have a (semi) normal life. She shares an especially close bond with Erina, with the two being very similar in a lot of ways.
Flora initially starts out as an infant, but due to her innate powers she ages faster than an average child. I'm a big fan of the "older alter ego" trope, so her magical girl form further ages her up (but only temporarily). Flora is a typical little girl, full of curiosity and mischief, not to mention love for her friends and family. Although her adoptive mothers wanted to keep her out of danger, Flora ends up becoming a mage to help them.
If you couldn't tell, Flora is heavily inspired by two characters: Hana Makihatayama from Ojamajo Doremi and Ha-chan from Mahou Tsukai Precure. Both are babies who are adopted by the main magical girl characters and then become magical girls themselves after aging up quickly.
NOTE: because so many bigger members of the Avarice Battalion are from the Omega clan, a big portion go to The Garden to celebrate the Omega Tree every Spring (a large symbol of longevity and legacy for the clan...before they burned down lmaooo!!!).
