At first, Naho is skeptical of the note; yet, after witnessing several events described to take place, she realizes the letter really is from her 26-year-old self. The note details that Naho's future life is filled with regrets, and she hopes that her younger self can correct the mistakes that were made in the past. The letter also warns her to keep a close eye on the new transfer student, Kakeru Naruse. Naho must be especially careful in making decisions involving him, as Kakeru is not around in the future. With the letter as her guide, Naho now has the power to protect Kakeru before she comes to regret it once more.

Ore dake Haireru Kakushi Dungeon

Despite his noble title, Noir Stalgia is at the bottom of the social hierarchy. Because of this, his fellow nobles oppress him and treat him like garbage. However, he possesses a rare yet powerful ability to communicate with the Great Sage, an oracle who grants Noir the answer to absolutely anything. After failing to secure a job as a librarian, Noir decides to join the Hero Academy. He knows he must become stronger to enter the institution. The Great Sage advises him to explore a hidden dungeon deep within the mountains. There, Noir meets Olivia Servant, a beautiful yet enchained maiden trapped within the labyrinth. Olivia bestows upon Noir a set of ridiculously powerful skills that grants him virtually total control over reality. Naturally, there is a catch—every time Noir attempts to use his powers, his life points decrease, putting his life at risk. To replenish his energy, he must give in to worldly pleasures such as kissing his childhood friend! With his newfound powers, Noir begins his journey as a student in the Hero Academy, meeting new acquaintances and helping them through the dire situations ahead.

Ore dake Level Up na Ken

Humanity was caught at a precipice a decade ago when the first gates—portals linked with other dimensions that harbor monsters immune to conventional weaponry—emerged around the world. Alongside the appearance of the gates, various humans were transformed into hunters and bestowed superhuman abilities. Responsible for entering the gates and clearing the dungeons within, many hunters chose to form guilds to secure their livelihoods. Sung Jin-Woo is an E-rank hunter dubbed as the weakest hunter of all mankind. While exploring a supposedly safe dungeon, he and his party encounter an unusual tunnel leading to a deeper area. Enticed by the prospect of treasure, the group presses forward, only to be confronted with horrors beyond their imagination. Miraculously, Jin-Woo survives the incident and soon finds that he now has access to an interface visible only to him. This mysterious system promises him the power he has long dreamed of—but everything comes at a price.
