"Let go and scream Tatsumi with all the fire in you soul!!!!"
― Bulat (Akame ga Kill)
The ability to possess an uncommonly potent soul and gain highly formidable abilities as a result of the soul's power.
User has a strong soul that is equivalent to the power of many souls which comes in handy in situations that tests one's spiritual fortitude and grants spiritual abilities. The user's soul is unable to be bound by anything and lives free without anything holding it back. It is also strengthened by the user's desire to get what they want, no matter the cost.
Though resistant, a user's soul can still be manipulated and even absorbed with enough effort
