The adventures of a Demon King who awakens 500 years after his defeat in a futuristic world.

At Eden Hall, each glass has a story.

A team of assassins exacts a bloody retribution on Joe Logan – a former ninja who escaped his clan – and his family for betraying their ancient code. Rising from his seeming "death," Joe will re-emerge as his former self – Ninja Kamui – to avenge his family and friends and bring down the very clan that made him.

Traumatized by a childhood incident with a friend who took exception to his love of traditional dolls, doll-artisan hopeful Wakana Gojou passes his days as a loner, finding solace in a room at his high school.

In this spinoff series, Rimuru gets his hands on a notebook and decides to compose a record of his many adventures. But where to begin?

Bell Cranell is a rookie adventurer and the sole member of his dirt-poor guild founded by the petite goddess Hestia. Adventurers come from far and wide looking to strike it big in the massive labyrinth known as Dungeon, located beneath the city of Orario. Bell is more interested in picking up girls than Dungeon-crawling, but his reality check comes sooner than expected. Saved from a brush with death by the beautiful, renowned adventurer Aiz Wallenstein, Bell falls head-over-heels and sets his sights on winning her heart, but she's not the only woman he's caught the attention of, for better of worse.
