That little reimyu puffing up on Flan's hat is the best
Don't think it's puffing up, resisting wind pressue more likely.
Reimyu hanging on for dear life is so cute.
Where did the Reimyu come from ?
Reimyu is Flan's sidekick
You have to read the other half. Reimyu is her little friend whom was one of a few yukkuri who did a home invasion on Flan's owner's house. For some reason, Flan spared the little one after killing the parents, and the little one seemed to look up to Flan like a big sister.
*sniff* Flan surely would've made miss proud *sniff*
