Kaiser reincarnated as a student at one of the famous universities in Tokyo. He's a student of the student exchange system conducted by Japan and Germany.

Kaiser's eyes accidentally found Ness as he walked down the corridor, and without realizing it, suddenly he grabs Ness's arm.

"N-ness?" His voice implied with sadness and regret.

Ness didn't understand what's going on, he didn't know this man, but his heart felt a bit tight when he saw him, and he felt so familiar.
