Siiiiinncee I had to post this separated from the others, I'll give a bit of a fun fact about Yui's design:
As you can see, her vest it's pink, but in the picture from two years ago, it's green, well, it's a representation of how she was closeted, or, in other words, didn't show her true colors and hadn't bloomed yet, like flowers!! Also, Yui-chan it's in the flower arrangement club
Kusuri's brand new lab rat
Jokashi dorodoro is a lazy first year girl (same class as ahko and suu) who's usually found napping or reading science magazines. "Why wasn't she in the science club since the beginning?" I hear you not asking WELL THAT'S AN EASY QUESTION!!! She simply didn't know of its existence since she usually spends her break time napping in school
Satsume shado A third year student who wishes to become a filmmaker and photographer someday, due to an unknown hability, she can manipulate and move the "camera" of the fourth wall, which means, she can manipulate how us, the audience, see the scene, she's also constantly Looking directly at it, which means that unless we're not near her, she will look straight at us. Same class as saki
Ryuga miato, the visual artist They're a charming person that enjoys expressing themselves through visual arts (paintings, sculptures, sewing, etc) They act mostly as a mediator but can also be a straight man/tsukkomi
Hibiki Ritsu (i'm posting this here cuz I still haven't drawn them) A high school student from class 1-1, member of the dance club and one of the best dancers amongst them, the twist, who could think that such a skilled dancer would have such horrible reflexes, the moment they realize something is coming their way it is already crashing against their face, that's why ahko always has to apply her "pain pain go away" on them during PE class.
Yui hanasaki, third year of middle school and classmate of kirb- I mean, Kurumi and Momiji, she enjoys doing flower arrangements and flowers in general, using flower language to express her emotions or hide messages in plain sight, like her love declaration for rentarou. After meeting the family and explaining her history, kusuri developed a drug that allowed her to become 100% female without requiring any surgery, the drug is as strong as kusuri's failed immortality drug so it won't wear off in a loooooonnnng time unless she takes an anti-drug (which, if you've seen the series, will only work for some minutes), due to this, Yui has become really grateful to kusuri, being one of the few that actually respect her. (Sorry I didn't get Yui's picture my internet connection it's really low)
He's really cute so I wanted to draw him in some cool clothes ehheheheheheheheh ✨✨✨
Btw the original concept belongs to u/VoidOfLOVE (if you read this, imma tell you, I LOVE HIMMMMM)
