The transmigrator, Natsukawa Tiger, is 18 years old (?), mentally 30 years old (?), and his actual age is unknown. He is a young man who inherited the Holy Sword from King Arthur, a Star Sword Wielder with a body almost identical to that of Princess Arcueid of the True Ancestor, a candidate for Earth's Ultimate Origin, a well-known street hustler in the Clock Tower's parallel world, and a super-professional savior who has saved the world countless times! After saving the world yet again, he sincerely decided the following: [Even if Alaya and Gaia kneel down and beg me next time, I won't save the world!] [I want a vacation! I want to retire! I want to retire!] [Want me to save the world? No way!] Then, after getting married to his female brothers, only four years passed. Natsukawa Tiger, the human form of Arthur, the designated father of Alaya and Gaia, transmigrated again!

Natsukawa Tora transmigrated to Type-Moon. Lacking magic skills and connections, he was busy working odd jobs, initially thinking he'd be the most pathetic transmigrator. But everything changed after he was chosen by the Holy Grail and summoned King Arthur (Old Saber). Especially after the Holy Grail War ended, and Old Saber became his [Special Forces Machine], turning him into Old Saber Superman. ...On a certain day, in Chaldea, in the same familiar corridor, around the same familiar corner. "Sajyou Aika, don't come any closer! I don't know Arthur, really! -- Emergency call!" [Being being teased by a friend's old face [I'm telling you, Souji is super cute]]

Alexia had always thought that her whole life would be like this. She could not fight against the Honkai like the Valkyrie. She could only work as a data organizer under Bishop Otto, receive her salary every month and wait to die. That's fine, the worst case scenario is letting his childhood sweetheart Bianca raise him.

Until one day——

[Do you desire power? Yes or No? 】

Such a sudden appearance in Exia's field of vision eventually led him to embark on a path of no return as a professional world saver in countless worlds.

"It's really not that I want to save the world, but that I saved the world without knowing it."
