Oda Nubunaga

 

Professor Oda's son has a challenging name.

Nobunaga, however, is nothing like his 17th-century namesake and has nothing of the Demon of the Sixth Heaven about him.

Oda is an avid otaku, a lover of morning runs and good food.

He secretly (but not too secretly) has a crush on Mikazuki Sazuki.

He doesn't excel at anything except cooking, but he is well-respected and beloved among the other students for his good nature; he aspires to become a famous chef.

Spoilers - read to your own risk:

Nobunaga was artificially created to be a receptacle, perhaps even a trap, though he doesn't know for whom.

Even though he bleeds, eats, cries, and laughs, the boy is actually a homunculus, no more and no less than Professor Celeste.

He is a clumsy and awkward boy, with a highly developed sense of time (he can sense the passage of time with the precision of an atomic clock) and limited control over it (but these are completely unforeseen events).
