At the time of his accident at the age of 7, Kaizō was also attending the Genius Cram School, a local institute for prodigies in various fields like sleeping or fashion.

Now the science club constantly runs into people that also used to attend that same cram school and display even more eccentric behavior than Kaizō himself.
