Lolo was sweet and relatable, Leorina was a strong and cool anti-hero, but why is no one talking about Tat?
Tat is super cute, incredibly loyal and caring towards Leorina, and has one of my favorite designs in the series. Her splitting in half thing was neat too (I'm a sucker for literal duality in characters.)
In conclusion: Tat is best girl, all others see yourselves out.
(Also, she didn't have the biggest role, but for some reason I always liked Granny from DtP.)
