(Arknights + Kamen Rider + Ultraman Blazer + a large number of original characters.)
When Shuka appeared in the history of the continent of Terra, when the cyborgs with masks appeared and shuttled through the mobile city, when the wild giants roared loudly on this land. Fantasy and reality, romance and sadness. What kind of sparks will come out of the collision of all these. (This book not only has other works that talk about fan characters but also original characters.) (Don't worry about the combination of world views, it won't be too different.) (The protagonist does not know any content of Ark)
