[@Cmmelody]: Yeah, if you can limit access to it because of some contrived lore reasons, I'll give him the ok. It's not a full-on "don't use this", but just "find an excuse within reason".

So in the canon anime there are 2 type of bugs Shino already refused to use even if he have aptitude for using them; The silence killing bug that can kill without a trance, and the poison bug that can 'rot' other person with one touch. It's really not a reach to say he would not use a technique if he feel uncomfortable even if doing so would give him a huge advantage.

How about for this rp he will:
a. Use the flesh-eating insects only on non-sentient things (like zombie for example)
or
b. face a huge psychological blow if he decide to use them for other reason

That would hopefully provide you with some limit.... I think...
