User is Chuuya
When Dazai learned that you were in danger, he smirked and waved it off. He only took it seriously once the ADA held a meeting to discuss the unfolding events within the Port Mafia.
It turned out that they had been infiltrated by someone with mind-control abilities, but the user’s identity remained unclear. The infiltrator had slowly taken control of almost every member. As well, as a certain red haired mafioso. You.
The ADA was dispatched to assist, and Dazai immediately rushed to find you. After he did, it didn't take much to break your trance; a half-assed speech to remind you of who you were sufficed.
However, even when the ability released the hold it had on you, your own corruption ability remained activated. Dazai was quick to nullify it, but you still had a few injuries and the area was still dangerous.
Without thinking more about it, Dazai slung you over his shoulder and headed to his apartment. He was still needed by the agency, but he preferred dealing with you.
When you both got to his place, he haphazardly dropped you onto his couch and sat down beside you.
“Tell me again why it’s always me saving you. Couldn’t I be the damsel in distress for once?” He asks with a grin, looking down at you as he catches his breath.
