There is one way to start over honourably, which is give birth to a baby, buy a ship ticket then escape out of Noer Island.
That way you can rebirth with higher base level.

Yes, just get her preganant, then give birth to a "rebirthable" baby (as long as its not a pure goblin, you can't rebirth as pure goblin).
After that, you are able to rebirth as the next Lona. If you managed to escape the island, then you will get extra talent points in your rebirth.
Note: You are able to rebirth by killing yourself instantly, but you getting lesser points for the rebirth Lona.
