Strobo

Misumi died. And now she's sent into Limbo for the sin of dying before her parents. And she's not alone: others like her were sent to Limbo where they were told that they have a chance to live again. With one gruesome condition: Using what killed them and turning them into "Deathly Weapons", everyone must fight and kill each other until one person is left standing.

From the pen of Tsukinowa Kosuke comes this Supernatural Action Adventure about dead kids killing each other for the right to live again.
