Fate: Salvation

The protagonist has transmigrated twice. First, he transmigrated into the world of Honkai Impact 3rd as Kevin, but he had no golden finger. He loved that world too much and was afraid of changing it. Before he died, he was summoned by the Holy Grail to join Kiritsugu Emiya in the Fourth Holy Grail War. But Kiritsugu had no command spells for him. Summoned alongside King Arthur, he became the eighth member of the seven classes.

(This is a very short novel. I'll write the Fourth and Fifth Holy Grail Wars, as well as the Fake one. I'm not sure if I'll do a good job, but I'm using it to practice my writing. I'm sure I'll do better with the later parts.)

Note: This story doesn't focus on Kevin, since he's far too overpowered. If I made him the main focus, there'd be almost nothing to read. Besides, I'm a complete beginner and can't write him very well.
