2*: Strawberry and her various heart-pounding sound effect lines (dokidoki, wakuwaku, kyun kyun, etc.).

3*: Asagao--I mean, Ipomoea and her onii-chan~
Alstroemeria is good too, but her "take damage" quote gets grating real quick.

4*: Di Yu calling herself Mokou and ending all her sentences like a question desuu?

5*: Kind of a tough call since I haven't heard a lot of them, but I'll give it to Lavender.

6*: Daisy's running! Laughing! Falling!? And all her other great quotes.
