Battle: Honkai X Elf!

Cangqiong City is an area where space earthquakes occur frequently. The residents who originally lived here should leave the city early to find a new home. But a brave young high school student, with the help of 'Ratastock', successfully rescued and met one 'elf'. Because the 'elves' were all captured by the youth, the supernatural phenomenon of space shock did not occur, and humans did not have to rack their brains to leave this dangerous city. The name of this heroic young man is Itsuka Shidou, and I, Shigure Lengyuan, was originally a greasy uncle who traveled through time in the battle in modern times. I thought I would be the protagonist of the battle, or similar to Mr. Shidou, but I didn't expect that when I traveled through the battle, I would turn out to be just a sidekick, and could only admire the goddesses in my heart from a distance! I thought I would just live my high school life in such a muddle-headed way and then die alone like in real life, but I didn't expect... This novel and its characters are purely fictitious.
