Nonsense. Issei can do a lot more being the way he is with his sacred equipment. If he didn't have one and had to live like a normal person, it would make sense to try to change it, but as a reincarnated devil he doesn't need to change.

This explains how he acquired resistance to poisons.

You let him die to join your group and things went wrong, didn't you?

Why does it always seem like there are veiled threats when she and her group speak?

It seems difficult at his current level. To make matters worse, without any support as he gets stronger, surviving becomes more difficult, especially if someone finds out he has a special power.

Yes, he would become the perfect test subject. A special power unrelated to sacred gears, with no one to support him, a rookie who knows about the future but no one would care about his disappearance. A perfect test subject.

Rukia is clearly a priority, huh...

Does that change the fact that they chose to exterminate a race?
