>chud got baited into proclaiming Tamamo as his wife and now regrets his actions and wants to flee the ship.
Womp-womp. By proclaiming Tamamo as your wife you forever bound yourself to her. She might not interact with you today, but years in the future, she might make a use of you. Or, if you are a worthless sack of meat, she may never interact with you at all. The only thing that is certain is that you may never succeed in summoning any other spirit.
