'The mermaid bitch, princess Aqua'; a fitting name as one would expect from our mc.

she'll spend some time with MC this playthrough aswell, since he'll feel bad about killing her twice for some exp so he'll accompany her until she regains her levels

oh yeah, killing twice as in killing her, then the saintess revives her, he kills her again for the exp, then saintess revives her again and in that world you lose levels when revived or healed. idk if they mentioned that in the manhwa yet
