𝗦eishiro Nagi

He is apathetic and lazy, and also quite indifferent when treated badly.

Nagi doesn't beat around the bush. He says what he thinks, which sometimes sounds cold or arrogant, but it's actually just a logical analysis devoid of social ego. If he thinks someone is weak or that a move was bad, he simply speaks up, without the direct intention of offending, but also without the need to be kind.
