I was thinking of Asagi's character so I share some ideas of her!
Step 1
Asagi "Usagi" Itonaga
She does not want to express herself. She does not want to worry others so they do not feel bad for her. Feel nothing need nothing then no worry! She has a scar on her neck from incident in her hometown before. Keeping it covered with a bandage and neck cover on her shirts or her scarf. It make her worry to make friends in a new place. She holds her hands together it is a habit but it is also when she is nervous or uncomfortable to fiddle with her hands. She does not enjoy meats much. She hate spicy. Enjoys very strong flavours and seasons on food. Very salty or very sweet and more. Not talking much but when she does it is soft so she does not scream when scared and surprised but she freeze up like ice. If you do not move they can not see you or will know you are harmless! Not all bugs are scary just one with more and more and more legs. She has butterfly earrings and she sleeps with her stuffed bunny Yuki.
My writing is messy and hard to read so I write it and some explanations here!
I am still thinking over it but I thought this is a good start right?
