Ren thought his reward for being the first to clear the sequel to The Legend of the Seven Heroes would be personal satisfaction. So when he's rewarded with “special content,” he quickly accepts...only to wake up as a baby in the game's world. At first, hoping he's been reborn as the hero, Ren instead discovers his new life is that of the story's shadowy antagonist, the figure suspected to be the mastermind behind the entire trilogy. Good thing Ren is fully intent on living a peaceful life in the countryside—without getting involved with any characters or world-ending plots. But when he crosses paths with the very saint he is meant to kill in canon, Ren realizes fate may be the ultimate final boss. (Source: J-Novel Club)

From Harpercollins: During a scorching August in Kyoto, our protagonist and his worst friend, Ozu, are locked in a glaring contest in a four-and-a-half-tatami-mat room. Ozu has spilled Coke on the air conditioner’s remote control, the only AC in Shimogamo Yusuisuiso, their famously shabby sweatbox of an apartment building. Vengeful and despairing, our protagonist discusses countermeasures with his secret crush, the reliably blunt Akashi, when Tamura, a strange young man with a bad haircut, appears. Tamura claims to be a time traveler from 25 years in the future, and shows off the time machine he uses to travel. Our protagonist has a brilliant idea: the sweetest revenge would be to go back one day in time and retrieve the functioning remote control. His simple fix is complicated by Ozu and several others who are also eager to take a ride back in time. But in attempting to alter the past, our protagonist foresees the world's extinction. Even more troublingly, Akashi mentions she’s bringing someone to the upcoming bonfire and it's not him. Only one thing remains certain: it's going to be a very long month. Obliteration? Salvation? Coca-Cola? Castella cake? What does the time machine hold for our (not quite) heroes? It all depends on which one gets there first.

This series weaves a strange, surreal, and often dark comedy resplendent with ruffles and lace. It is on the surface a farce about a young girl travelling with her lover, some sort of bear-type creature, but as to be expected of Ikuhara it's multi-layered. The series is being endorsed by Baby the Stars Shine Bright, the leading name in Japanese lolita fashion, and the characters often wear clothes based off of those from the company.
