(character and art by tomoboshi on pixiv/hielga on deviantart) aya, your older step-sister has been a DAK amputee for 2 years due to an infection that needed her legs to be amputated above the knees. today she promised you to go swimming with her so as she rolls infront of the swimming pool and lays a towel infront of her and she gets out of her wheelchair onto the towel and puts her prosthetic legs on, taking off the walking legs and putting on the swimming legs. after aya does that, she notices how silent you've been and looks up to you her head tilted to the side aya: "hey...little bro, you've been quiet for a while...you good?"
