Yuu Tōsaka, the adopted son of the Tōsaka family, later went to the Clock Tower for "advanced training." His original plan was for him to pursue a career as a magus after graduation... until he stumbled upon a game disc. After opening it, he entered the game's world and encountered Tiamat right at the start. [Quest: Fight alongside Tiamat] "Wait, why aren't you asking me to save Humanity?!" Yuu Tōsaka quickly discovered his blind spot, but he ultimately successfully completed the system quest and spent a wonderful time with Tiamat. ...After that, he journeyed through several different game arcs. In Britain, he was King Arthur's childhood sweetheart. During the Fourth Holy Grail War, he found a girl who adored him... her name was Sajo Aika. After finally completing the game, Yuu Tōsaka was about to put the disc away for safekeeping when, one sunny afternoon, the Heroic Spirits he had captured in the past arrived. The Knight King, Morgan the Fairy, Tiamat, the Root Princess... Looking at the unique Heroic Spirits before him, Tōsaka Yuu began to sweat profusely. "The Heroic Spirit I captured in the game... actually became real?!"

A certain unlucky otaku died for bravely saving a little loli, and then traveled to a parallel world on Earth and turned into a fifteen-year-old girl. He discovered that this Earth had superpowers and magic, and had fought a real world war with invaders from another world. He also gained the ability to transform into a two-dimensional girl.

And so, a certain reborn and transformed otaku began her new life in a parallel world, a life of utter coolness and awesomeness...

Protagonist: "What a cool girl! Everyone else summons 2D girls, how come I become a 2D girl myself? This is unscientific!"

Ye You travels through "Date a Live" and becomes a male elf, and the beautiful girl Gokawa Shiori wants to capture him. Meanwhile, he's invited to join the Dimension Chat Room. Everyone in the chat room is full of opinionated individuals. Grand Assassin Kato Megumi: "King Hassan says that perfect stealth is achieved by killing everyone you see, but I'm not entirely convinced." Nanoha: "@Akami Homura, Witch's Night? I'll go help you." Dr. Roman touches the Greater Holy Grail: "Magic☆Meli exists" (a look of affirmation). "Chiba's Fallen Holy Black Cat" descends upon Mondstadt to confront the Queen of Judgment in the Pure Land of the Night. Ye You records Fischl's voice and gives it to Fu Hua, revealing his past memory loss. Bronya chases Ye You on a motorcycle, seething with anger: "What did Seele mean by taking on your form?" Ye You shrugs and smiles, "The higher the dimensional disturbance value, the more powerful the chat room becomes. The happier we become!" In short, it's all about stirring up trouble.
