I was already a little hesitant because of the MC's main ability, which is a summoning style, which probably makes the MC in itself useless, but now the MC will only have thirty percent of the knowledge, if the knowledge is in chronological order, it means that the MC only remembers one more than the beginning of the story, which means he's barely reached Shippuden in knowledge, all the most important information is almost exclusively at the end of the story. Anyway, I probably won't read this, a reincarnated person without knowledge is useless.
This I just a really roundabout way of avoiding the "iF He alReAdY kNeW hE sHoUld dO tHiS AnD ThaA". Which is the dumbest reason why you should change the story and even if he knew everything in the story there is little he could do to take advantage of his knowledge unless he is in very specific situations.
las 10 sombras me parece la habilidad más epic de jjk más por mahoraga que me encanta y me parece el personaje más roto está bien que dirán no sukuna o gojo lo vencieron pero tengan en cuenta que el bicho se adapta y después ya no le hace na dale tiempo y es invencible en peleas a la larga es el más fuerte
