THE_RED_FURY

Because they always have to nerf the mc, just because they don't plan the story well

Create a sword to extract Isse's bostedgear. And use it or give it to someone else. Issei is a problem

The author would be a legend if he kills Bell, who is an obstacle in the story, there cannot be two protagonists.

It really is the best option. Although it's cliche since if Issei had bosted gear it would be a problem

So the mc has no real relevance since the canon remains the same

Haki the ultimate power system

Time skip???
