Honestly? I hope not; we already have more than enough OP character, I like to see a normal, or even a "role player" one.
For example, she could get a small contract with an alchemist for potion disposal, or the slime secretion could provide a small bonus to the potions crafted using it, or provide small healing; "small" being the key word in whichever benefit she gets.
Or maybe the slime could reproduce the effect of the potions you feed to it; in this case it should only replicate the same or worse version of the effect, and you should need to feed a lot of potions before being able to replicate the effect.
OP characters tend to become assholes, being involved with assholes, becoming harem protagonist or all of the above.
