Essence of Gacha (CYOA v2.2 Uchiya Version [My version], Questions about the acronym CYOA? Search Google!)
This is the essence on which the power of the MC is based, however, I will make some small modifications for myself with a little inspiration from today's gacha games... even more so for this fanfic, which will have strong social development due to the characters that will be introduced.
The development of Itachi's powers will not take long, but it will be appealing so that the work flows well. The universe will have a crossover between Marvel and some anime that will be mentioned throughout the work, and these are universes with which the protagonist will need a lot ofraw powerto deal with in the middle of the journey.
(NOTE: The items that the MC receives will be from their previous world and their current world. When the protagonist encounters a character from this world, the Gacha will adapt and there will be chances for the MC to acquire that character's items as well.)
