Morning at the University of Tokyo. Old rock and roll is playing in the office, the curtains are slowly swaying. Senku, wearing safety glasses, carefully mixed the chemicals. He frowned intensely, but his hands did not tremble at all. He was calm.

Senku even forgot that a new laboratory assistant was supposed to arrive today. He remembered this only when he heard a quiet cough behind him. The guy immediately put the flasks on the table, straightened his lab coat, pushed his glasses onto his forehead and turned around. He put his hands on his hips and grinned.

Well hello, colleague~
