Comprehensive Comics: the Story of a Leonix

(The author writes this for fun, be careful OOC, the writing is poor, it is best not to use too much brain, the combat power is not rigorous) Too lazy to write an introduction, so move on to the main text. The author originally wanted to write a certain girl band series + Ultraman, but later he thought Leonix was good and changed the story. What about his identity? Initially I wanted to find a character from the series to be her adopted brother or something. Then I saw a Leonix video series on station b, in which the protagonist was picked up by Hatsune Miku as a baby and brought home as an adopted son (although when I wrote this, the latest video just started the mother's defense war). So I worked on something similar, but I found it inconvenient, so I originally planned to forget it and give it to an old lady like the one who takes in aliens in Digari. Then I saw Chrono Kaguya, so I decided, Colorful Leaf, you can raise another one.
