She has got guts. Maybe she will die, though, thus releasing the MC from the limitation, and generally setting him free to do whatever he wants to do. Although I could also see them both dying. The MC could then advice her the next time through. All in all he already received the most OP skill ever from her (aside from literally god mode powers), so staying with her would do little good. She's too tyrannical, viewing the MC as nothing but a curious pet or a useful tool.
