Eden is her first power and is presumably her primary ability. Eden's power is summarized by Reine as "the power to redo the world until the user gains the desired result". Using this power, Rinne can create a large field where all the events inside the field can be manipulated and redone as many times as she desires. This is the power that Rinne used to hide the tree that functioned as the core of the Eden, by manipulating the residents of the Tengu City into believing it to be the city's new monument: New Tengu Tower.

Rinne also used this power to make herself be Shido's kind childhood friend that was always with him ever since they were kids. According to Reine, this ability could be seen as an Angel, but on a scale that far surpasses one. Paradise Lost is an ability that allows her to control the roots of the tree that is the core of Eden to attack her enemies. Rather than hurting the enemies physically, the roots take their consciousness. Rinne used this power to defeat Shido and the Spirits.

Rinne also has the power to summon multiple guardians, cloaked beings with humanoid forms and 6 wings that wear either a red, white, or black cloak. Individually they are powerful, but not as powerful as an unsealed spirit. In each route, except Rinne's, the chosen girl and Shido will have an encounter with these Guardians.
