I personally sometimes like to imagine how one work will perform in another work, but as we all know, comparing combat power across works is a hooliganism, and sometimes arranging two people from different works to fight is easy to get scolded no matter who loses or wins. So, alas, I had a genius idea. I simply wrote some second creations myself and put my own second creation protagonists together to fight. It was perfect. I'm too lazy to open new books one by one, so I just put this one in all.
Currently I am writing (Cardcaptor Sakura, Bears, Fate, The Adventures of Jackie Chan, Little Nightmares). If you are interested in the content, you can jump to the corresponding section. One volume is a story.
However, at present, I have mainly updated Little Nightmares and the other few have only written the beginning.
