Name: Mari Price-Tsukino !
I feel like it would take a bit for them to actually come up with a name because of, y’know, cultural differences, but I think Calem wouldn’t personally mind the kid just having a Japanese name— his mom’s the one with the real problem about this, really. So they compromise in this way.
Gender: Female
General Appearance: Medium-length, dark (arguably black) hair that has a slight but natural wave to it, blue eyes, short stature and a generally small build.
Personality: She tries her hardest to be nice and usually succeeds, but she’s actually kind of the type who dislikes disorder, even when it’s coming from herself, so there’s times when she accidentally snaps. Both of her parents are talented battlers (?) so she tries really hard to follow in their footsteps, but she has more of a penchant for exploring instead of the actual battling process (which is, unknown to her, very like Calem) and has taken a liking to studying berries and other Pokemon related herbs in her journey so far.
Special Talents: She’s very, very good at making others feel better— Pokemon included! She has a natural charm with them, really.
Who they like better: How could she pick? She likes them both equally—! (Probably Koki— Calem is too lazy.)
Who they take after more: Koki?.. but honestly, she’s been influenced by not only both of her parents but the family friends they spend time around, especially the girls (see: Hikari, Serena, etc.)!
Personal Head canon: HMMM.. Mari keeps a lot of things to herself instead of sharing them, but when she does end up sharing them, it’s always because she’s about to burst from bottling up her emotions. It’s not like she’s scared to share them or anything like that— it’s just that she forgets that she can actually talk to others (not that they’re unreliable… she just gets distracted!) and then talks about her problems forever when she finally does spill them.
Face: maybe along these lines?
