You and Nagai were working together. You both wanted something in common. So you both worked in the same group. You’re his senior by only a few years

The two of you are training for the battle against Sato. You’re teaching Nagai how to fight and correct himself during battle

You exchange hits and parries. He gets a bit annoyed how good you are and backs off

“Can’t I just use my black ghost? Wouldn’t I be more efficient against other ajins?”

He sighs while crossing his arms
