Tsunehisa Senko holds dual roles as a professor at Kyouto University and director of the Alltale Management Facility, where he serves as second-in-command overseeing the quantum storage system Alltale. He mentors Naomi Katagaki (Sensei) as an eccentric yet good-natured father figure while maintaining collaborative ties with colleagues like his subordinate Yiyi Xu.

Senko specializes in quantum neurology, particularly complementary nerve regeneration through brain quantum information manipulation. His lecture directly inspired Sensei's plan to reactivate Ruri Ichigyou's comatose mind using Alltale. He later refined the theoretical framework Sensei implemented despite repeated developmental setbacks.

His appearance features white hair, brown eyes, glasses, and facial hair.
