Hundred

"Hundred"—that is the only weapon that can oppose the mysterious life form "Savage" from visiting the earth.

The protagonist, Kirasagi Hayato, aims to become a Martial Arts Master using this Hundred. He managed to get into the battleship university Little Garden.

However—

"I wanted to see you, Hayato!!!"

"H-How do you know my name?"

Around the roommate, Emil Crossford, who somehow knows him well (?), Hayato gets an uneasy feeling.
