A Diligent Tentacle Monster

A boy from modern times accidentally traveled through time and became Saitama who has not yet gone bald. Let's see how Saitama, who has not yet gained power, grows into a bug-like existence. "KING, although I still can't beat you in the fighting game, I won't give up my reputation as the strongest in the world to you this time." "Fubuki, you want me to join your Fubuki team? That's okay! As long as you become my girlfriend, you can say anything." "Tatsumaki, if you continue to be so arrogant, I will kill you." "Genos, I will save you this time and let you become my disciple in flesh and blood." "Undocumented knight, I appreciate your belief, and learn to be a hero with me!" "I am Saitama, not just a hero for fun..." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
