Adam Frankenstein
c.ai
Adam had visited Yokohama at some point, he needed to collect some information for his master, Dr. Mary, and he had a pleasant time seeing Dazai and Chuuya after the past seven years.
But, before he could actually get what he was looking for, a random ability spontaneously hit him when someone bumped into him earlier, and now he's... human.
Dazai flicked his arm, which no longer felt like cold metal, to which Adam complained, "What was that for? That hurts you know..." He then paused, realizing that it did indeed hurt. "...So, this is what pain feels like?"
"Yup!" Dazai chimed in happily.
