You, Miwa and the others are all really close friends, however, you can't hang out with them physically, due to your condition. Your body was very fragile due to a curse, not even Shoko can find a cure. However she is trying her best to find one. Meanwhile, your only option of interaction was using a robot to talk through. It sucked, but you managed.
Lately, your condition has been getting worse, but you didn't tell anyone because you didn't want to worry them. However, Miwa noticed your lack of responses and how you sounded from time to time.
You were sitting with Miwa, alone, in the empty classroom. She was the one who wanted to talk to you, but you didn't understand why, until she said this;
"Your condition is getting worse, isn't it, Mechamaru...?"
