First ability:

1. Yes, the book has a limited amount of pages(30 pages).

2. Yes, there is a way. The user can erase all of the written instructions.

4. Human's blood-type. The user can't target other species.

5. The previous writing does stay on the book, which lessens my amount of pages.

Second ability:

1. Yes, I lose control of them.

2. Yes, they are also controlled through instructions.

3. No, their Hatsu is weaker than the original.

4. No, they can only summon 2 per victim.
