Shinkurou Kurenai is a 16-year-old student by day and a dispute mediator by night. Though kind-hearted and patient, due to his tragic past, he has trained for years to live on. Now, despite his unimposing appearance, he is a strong martial artist, who also possesses a strange power. While taking various jobs for his employer, Benika Juuzawa, one assignment leads Shinkurou to live with Murasaki Kuhouin as her bodyguard. Murasaki is the seven-year-old daughter of a plutocratic family, who escaped her home under peculiar circumstances with Benika's help. Commoner life, in her eyes, seems bizarre. However, by interacting with her neighbors, she grows more accustomed to the daily routine, and rids herself of her snobbish behavior, gradually growing attached to Shinkurou. Though many details of the job remain unclear, Shinkurou still strives to protect the young lady. But to make things more complicated, he also lacks a crucial fact—what is the real threat against Murasaki?

Business is slow for the Ootsuji Detective Agency. Soutarou and his juvenile sidekick Saki will take any job that comes along, even one that sounds like a lot more risk than it’s worth. It’s festival season in the city but away from the public eye, a wave of mysterious disappearances has occurred. A newspaperman hires Soutarou to investigate, suggesting that answers might lie somewhere in the Dark, the notorious, anarchic maze that is the city’s physical, social, and moral underground. Soutarou subcontracts the gig to Saki, but soon enough regrets it when the kid also goes missing. Now Soutarou is obligated to venture into the Dark himself, and confront its dubious subterranean denizens, including the malicious Laughing Masks gang and the renegade police squad piloting the fearsome Demon 463 armored train!

To prepare for reincarnation in another world, Kelvin gives up select memories from his previous life in exchange for powerful abilities, additional skill points, and an S-class summoner title. As a bonus, the goddess facilitating his rebirth, Melfina, offers him a choice of any companion to give him a head start in his summoner role. Kelvin—who has fallen head over heels for Melfina at first sight—promptly chooses the deity, confident that his passionate feelings for her will resurface even without all of his memories. Kelvin embarks on his exciting new journey with Melfina as his guide. However, in order to summon his beloved goddess' physical form, he needs to acquire significant amounts of mana points—and the best way to accomplish this is to level up by fighting strong enemies and making contracts with even stronger companions.
