Peak Athlete: Ryuu's contract powers are especially useful because of his amazing agility, speed, endurance, dexterity, and natural strength.
Expert Hand-to-Hand Combatant: Ryu is extremely skilled in martial arts and is an accomplished acrobat easily able to do backflips and mid-air cartwheels without even a little effort in terms of physical strain. Ryuu's natural abilities are so impressive that even without his contractor powers Hei is easily able to take on other contractors. A combination of these physical attributes coupled with what appears to be the most powerful contractor power as well as a lack of obeisance arguably makes Ryuu one of the strongest character in the series.
Contractor Power Edit
- Molecular/Electricity Manipulation: Ryu possesses the ability to generate and discharge electricity through conductive media (i.e. he cannot discharge it through air or concrete) at sufficiently high amounts to kill grown men or short out a building's electrical systems. The power is more than simple electric shocks, as he can alter matter on the quantum level. He has shown the ability to transform integral particles on the quantum level. He is capable of special particle luminance, meaning he is able to change molecules similar to how humans are changed into contractors. This ability is also one of the most, if not the most, powerful and coveted powers known as it is the only one capable of altering gate particles at will. This ability is not actually his as he is really only human, but it was granted to him when his brother fused with him.
- Chronokinesis: Ryuu's ability is chronal manipulation, which includes temporal freezing of time and rewinding of events to an unknown degree. Elaborate usage of his power enables his to gain knowledge of future events, through a form of clairvoyance. Once time has been frozen around him, he can also pull other people out of the frozen time stream, while those still under her ability's effect will no longer detect her presence or movement.
- Obeisance: None. This inheritance means that Ryuu doesn't have an Obeisance unlike other contractors. The reason behind this is that he is actually a human who has fused with his brother a contractor, therefore he has no price to pay.
