A self-taught Magus and an avid fantasy reader ends up inside the Tower of God with Mordred's power and with Mordred's soul inside his Ignition Weapon as a result of his wish to the Holy Grail. ... Summary: The Main Character participated in a Holy Grail War and ended up being the final winner thanks to wit and luck, but at the cost of his Servant Mordred. As a result of his subconscious wish to the Holy Grail (it seems), he gained various powers similar to those of his Servant, his dead Servant Mordred was restored and took refuge inside his sword, and the two ended up inside the world of the Tower of God. Over time, he discovers that the Tower is exactly a place where he can fulfill his various desires and wishes as promised, growing more powerful and achieving more than just a single wish could grant him. ... It is mainly a Tower of God story. The only aspect from Fate verse is the MC and his powers. The goal for the Main Character is to grow his powers and live an interesting life in the new world. PS: Mordred is not a romantic interest. This is not her character. She is MC's platonic female friend and partner/Ignition Weapon for the majority of the story, since the base of her character design is a child seeking attention. The other girls from TOG are the heroines, and mainly Endorsi. I wonder what the response and popularity would be like. I also like the fact that the MC's powers here are quite straightforward, and it makes things easy to write.
