Spider-Man: Kizuna

A high school student named Yu Komori is bitten by a radioactive spider, which gave him spider-like powers.

In the year 200X, a supervillain who goes by the name Lord Gokibu wants to steal the fossil of the Insect King, 15 year-old Shou Amano uses his new spider powers to become Spider-Man J, to prevent this from happening. During his time as a superhero, he meets Japanese versions of Elektra, Dr. Doom, Blade, and the Fantastic Four.

Yu’s new high school is kind of awful. He’s failing his classes and striking out socially. Everything changes when he finds one of Spider-Man’s costumes abandoned in an alleyway. At first, it’s fun to put on the costume and play hero, but when powerful enemies appear, Yu quickly realizes he’s out of his element. Still, with the real Spider-Man nowhere to be found, the city needs someone to save it…
