Despite her low-key profile, Aine is the force behind Sakuya's on-stage charisma.

* ViolentlyProtectiveGirlfriend: '''Gender Inverted'''. DO NOT HURT AINE OR ELSE!!! There is nothing Sakuya won't do to make sure she is safe and happy.

* FeminineWomenCanCook: Aine has been putting in a lot of effort to polish her culinary skills, specifically focusing on pleasing Sakuya's taste buds. During her stay at Yuki's residence, she even managed to get hold of a recipe from Yuki's wife, Maria - a feat that she is extremely proud of.

* BrokenAce: He excels at anything he puts his mind into, whether it's music, acting, business, sports or modelling. At the same time, he is ''seriously'' screwed up.
* ButNotTooForeign: Half-Caucasian American. The only traits that reveal his American ancestry are his blue eyes and large frame.
* CharacterDevelopment: He went from a carefree and ReallyGetsAround man, to a faithful and more caring person, ever since he met and fell in love with Aine.

* FetishizedAbuser: Moreso in the manga, but in the anime he has his moments too. He's a Type 2: "TroubledButCute dude with a DarkAndTroubledPast and an even worse current attitude". He grows out of it with time and with Aine's love.

* JerkWithAHeartOfGold: Despite his notorious harsh attitude, you have to admit that he can, and become one, showing how caring and loving he can be to those close to him, especially Aine.

* SecretRelationship: {{Downplayed|Trope}}, as it's common knowledge in Λucifer that Sakuya and Aine are together. For a time, they attempt to keep their romance a secret from everyone else as a result of its somewhat UnequalPairing nature. {{Subverted}}, as the result of Tomoyuki hypnotizing Aine into thinking she's his sister Yumi and forgetting about Sakuya resulting in Sakuya almost dying to get her back, which ends up putting the media spotlight on Aine. Sakuya, despite recovering from his injuries, holds a press conference to confirm that he and Aine are together, that she is the love of his life and that he would do anything to protect her, all so Aine won't be blamed for his injuries. From there, things get more complicated as a result.

* DefiledForever: After being brutally raped by Yoshioka, her mind is left a total wreck, leaving her in a near-catotanic state.

It takes a lot of time, effort, and recovery (including Takayama's death in a car accident) for the young couple to return to the band in time to move to New York City.
