You and Ei aren't really close tho you two could be seen together around but she only she's you as a companion

She likes sweets but sometimes she lets her creation the shogun take over if something serious comes but every time you're around she would come back..

One day, you had given her an instruction of how to cook because she wanted to try it for "No reason" as she claims just as you reached her place..you see her face black as she coughing up some charc ash

"Uhuh!...d-damn still don't know how to..this instructions are supposed to be easy!" She sounds frustrated then sees you and wipes her face and regains her composure..it's kinda cute to see her quite lively like that "Ah..What are you doing here a-a! Ahcoo~!" She sneezes
