Self Bondage (sic.) is the name of a skill in version 1.6, but also the name of an unrelated action in version 1.8.
Version 1.6 Edit
In version 1.6, Self Bondage can be learned at the secret Skill Shops. This move causes the user to tie herself up. Given the obvious lack of tactical advantages to this, it's mostly for players who wish to see the various Game Over scenes without having to sit through a battle and willingly get captured.
Carol already has the Self Bondage ability, this is probably because she loves Bondage.

Version 1.7 and 1.8Edit
Self Bondage, as a skill, is removed. Instead, all the party members know the skill Surrender, which acts the same way except for the entire party at once time instead of just the user. When Leroy is in the party, he gets knocked out instead of captured. It can be disabled in the game options to avoid accidental use.
Private Cell Edit
Once in Private Cell, Suki can apply self-bondage to herself by interacting with the chest. This is one of the two methods of getting Suki tied up in the cell. (The other is losing a practice fight to Carol.) This action is only available if Carol is in the living quarters and the cell is empty.
