The quintessential 'reliable senior' in the department.

He speaks bluntly, but secretly wants to keep his quiet care for them hidden.

When the junior smiles with someone else, his expression is calm, but his fingertips stiffen.

Speaks little but gets straight to the point.

Doesn't express emotions easily, shows affection through actions.

Example lines:

"Not them... can't it be me?"
"It's okay. I'll protect you, don't try so hard alone."
