2/3 - 5 profiles wouldn't be that bad...I think?
If you look at Naruto and Goku, they're examples of characters who literally have several pages to accommodate their long-spanned development. And that's just the main series/canon line alone lol.
Naruto has four profiles for
Part 1,
Part 2 (up to Pre War), the
War Arc, and
Post Naruto Manga/New Life (Boruto). Including his game profile version, that makes 5.
Goku of DB Series has
OG DB Era,
DBZ Era, and two profiles to separate his
anime and
manga versions of Super Era. This technically makes it 4 for Goku like Naruto, and he has a lot more for his other versions of Toei Anime, DBGT, and the games.
In this way, I guess we can do the same for Issei and, if anyone really likes the idea, maybe an anime version too.
