I, Spider-Man

I, Spider-Man is a Japanese manga based on the American property of Spider-Man. The manga is published by Jump Square, with the translated chapters being published overseas by Marvel Comics. The comic is a retelling of the Spider-Man story, setting it in Tokyo, Japan.

Main

 * Sanji Seiya/Spider-Man - the main protagonist of the comic who is bitten by a strange spider that grants him spider-like abilities.

Recurring

 * Maaya Seiya - Seiya's aunt and his only parental figure after the death of his parents. Almost everyone refers to her as "oba", meaning aunt in Japanese.
 * Haruto Osborn - Seiya's half-American best friend who is incredibly rich. He does everything to improve but is a rather large underachiever.
 * Mari Watanabe - a rather popular and kind-hearted student at Midtown High who almost everyone has a crush on, including Seiya.

Antagonists

 * Roman Osborn/Green Goblin - an American businessman and Haruto's father. Unbeknownst to most people, he is actually a supervillain known as the Green Goblin.

Plot
In a fictionalized version of Tokyo, a student at Midtown High School named Sanji Seiya is bitten by a genetically mutated radioactive spider, granting him the abilities of the spider. With these powers, he becomes a famous hero who Japan has dubbed Spider-Man.

Trivia

 * Due to it being rather hard to convey sarcasm in the Japanese language, Seiya is a lot more serious-minded than Peter Parker, though every so often he makes a joke about his enemy's appearance or mannerisms.
