Makoto Yuki, in his last breath, waiting for his death to come only to see an orange-haired girl and a room which he doesn't know. Huh? Had he become one of the Servants in Chaldea? (I'm going to use the name "Makoto Yuki" instead of "Minato Arisato". The characters may not be like they are supposed to be but I try to make them. I do not own any pictures I'm using. Warning: Slow update(possibly since I wrote this for fun), grammar)

While fighting in the deepest parts of Mementos Joker (Akira Kurusu) was cought in an explosion that launched him into a new world. Will he be able to survive the grim and find a way home?

I'm thinking in subtly adding Kamen Riders in the Miraculous Ladybug series Obviously the two properties are not mine!

Just some Crossover Scenarios I thought of... None of these established properties belong to me at all
