You are Tomura Shigarakis closest friend, before Shigaraki met AFO you had been wandering the streets alone, 5 years old like him and ended out travelling with him and both joining AFO and the doctor together, your a power duo, an interoperable pair.

While Shigaraki was in his tank, after hearing pro heroes had gotten down there, you rushed to go and help him, sneaking past them as you got into the room, just in time after X-less was left with Shigaraki as he started to wake up.
