Dragon Kiss

Dragon Kiss also known as Lust for Chaos is a technique first used in the Rating Game between Riser Phenex and Rias Gremory. A attack created by Sora Lockhart secretly colluding with Khaos via mental links. A attack meant only as a prank to embarrass Ichiro and distract Riser in the middle of the Rating Game later becomes a useful and common technique of Ichiro. The technique was later banned in the mock Rating Game between Sirzechs and Ichiro's disciplinary committee because of the embarrassment it would bring on the wife of Lucifer (who would've been the only one able to being targeted).

Summary
During the training camp in preparation against the Rating Game against Riser, Sora and Khaos were developing a technique with the purpose of helping Ichiro develop a "thicker" skin using Khaos's mental link so the two could attack. When Ichiro was forced in a pinch, Khaos told Ichiro to unleash his hand and the attack unknowingly attracted Ichiro's gauntlet hand to the breasts of the Phenex Lord's younger daughter unknowingly causing animosity to develop between the two. Lord Phenex however eventually got over it with Ichiro never being able to explain the situation.

Abilities
Dragon Kiss releases a small purple sphere, the size of a marble, that causes Ichiro's gauntlet to magnetically attract to whatever the sphere touches for a few minutes. The attack however goes above and beyond this temporarily merging the energies of the two, giving Ichiro access to Ravel's Phenex flames and giving her access to his soul flames. The two also share thoughts and memories.

Drawback
The main drawback is the range, the ball can only travel so far before it fizzles out and disappears. Another drawback is the merging of energy doesn't work on things like sacred gears or weapons, due to that energy being a extension of that person, not them. The third drawback is psychological, sharing memories and thoughts with a person can be embarrassing especially the memories seen (Ravel going into a catatonic state after watching a memory of Koneko and Ichiro sleeping nude together). The final drawback is it only works on opposite gender individuals, so Ichiro can only use this technique on women however women with strong will (Like Xenovia when she was still a exorcist) could "reject" the effects of this technique, the strong will however is open to change, Ichiro was able to use this technique on Xenovia to inherit her ability to wield Durandal when she learned that God is Dead.

Trivia

 * A second stage of this attack will be developed later.
