When UPL went bankrupt, the copyright of Ninja-kun was temporarily taken over by Jaleco. Later, Jaleco also went bankrupt, and the rights of UPL works such as "Ninja-kun" were transferred to Hamster, and the rights of Jaleco works such as "Ninja Jajamaru-kun" were transferred to City Connection.

Tsutomu Fujisawa, who was an employee of UPL at the time, made a negative remark in an interview because it was released without any permission from UPL.
