OSMOS
Osmos are singular entities born from extreme suffering—from the fury, brutality, and agony of violent deaths. Every human can connect with an Osmo and, with training and vital strength, unleash its power.
However, the maximum stage, the Absolute Form, is a mortal contract. This fusion grants the host 100% of the Osmo's strength, but it is unsustainable: the Osmo consumes the user's emotions (such as rage and pain) and, when those emotions are depleted, it begins to devour the host’s body. It is a form of power that can be fatal unless mastered by someone of extraordinary strength.
