>>305894931: She's fun and mischievous without LULZ, SO RANDUM
2: Her design is a bit different than the other characters. Chipmunk did not kick down her door.
3: She has a loli body without being a loli. Well, not as much as Acerola, at least.
4: Familial center. Actual waifu material instead of raunchy sex two or three times then get bored material.
5: Resiliant and professional, despite her personality. Semi-tied to four, she holds down a household, is a fisherman, and works as a trail captain and doesn't seem particularly bushed. Kiawe on the other hand can't even balance being a Trial captain with a wageslave job at Mega-lo Mart, and Mina can't even manage to be a Trail Captain.
6: In as few scenes as she has, she has a very diverse and varied set of interests, hobbies, and other quirks.
Basically, she's not just cute, she actually has the groundwork already done for being a good choice for someone to rely on and share experiences with for the rest of your life.
