Riki-Oh 2: Child of Destruction

A Retelling of the prison arc of the manga RIKI-OH! The story follows Saiga Riki-Oh, a young man blessed with inhuman strength. After taking revenge against a yakuza boss who was responsible for the death of his girlfriend, he ends up in a maximum security prison owned by a private organization. The prison is divided into four blocks, each run by a member of prisoners known as the Gang of Four. The first member is a tattooed knife wielder known as Hai that runs his block in a mafia style family system.

The final member is a small man that use sewing needles as his weapons.

Hyoudo Riki is just an ordinary guy who likes to wear a tiger mask while Kung Fu fighting, which means he fits in real well at BATTLE ROYAL HIGH SCHOOL! Unfortunately for Riki, he's the doppelganger in our world of Byoudo, Master of the Dark Realm, and when a dimension gate opens between the two worlds, the evil Fairy Master tricks Byoudo into making an attempt to conquer out beautiful, and better lit, world. Now poor Riki is semi-possessed by his opposite number, and the minions of the Fairy Master are mutating his classmates into hideous lustful monsters. To make matters worse, all the inter-dimensional commotion has attracted the attention of a sword-happy exorcist and the heroic Zankan of the Space-Time Police! Which all means that Riki is about to take one bitch of a mid-term. The course is survival, and forget "Pass/Fail." This test is graded "Live/Die!"

Ever since the fall of the DARK organization, Jiro has been wandering everywhere and wondering if he would ever see Mitsuko again or not. During his journey Jiro meets a beautiful girl named Rieko who is protecting Akira, a little boy from the evil Professor Gill. Ironicly, he's the son of Professor Gill, but he is also the key to Gill’s menacing secret weapon and his plans to conquer the world.
