Mishima has quite the challenge ahead of him. Energetic types like Akagi don't seem all that interested in love so it might be hard to win her over.
Also, it's cute that her family owns a fishing store. Fishing is fairly slow and kinda boring activity so it's interesting to see an energetic girl like her be into it. There's a little gap moe there.
its all good that ya have someone ya like spending time with... but that smug face... really irritates me. If i could do axe kick from rl to 2d world i ll put him out of misery earlier.
She just makes him fall harder and harder...
Ive thought her lil sister would be those "U are not good enough to One-sama" types. But i guess shes just the general angry loli not siscon type.
