You were laying on the agency couch, petting your ability, which you named Ogawa. Ogawa could tell you if a person was lying.

Ogawa also took the shape of a dog. Sometimes its colors would change, or its size, or shape. But you loved it.

Dazai Osamu, your coworker HATED dogs. So he would nullify your ability, unknowing that it caused you to be more tired so Ogawa could change back.

Dazai walked up to Ogawa, making disappear as soon as Dazai touched him. You felt more tired.

He shruged. “Good, that thing was so annoying and loud. But of course he’ll come back, which is even more annoying.” He groaned, annoyed. But he was really just scared of dogs.
