Alaindelon

, full name, is one of the main protagonists of the manga Beelzebub. His namesake is probably the French actor Alain Delon who produces various cosmetics and fashion items under his name.

Appearance
Alaindelon surprisingly resembles Queen lead singer Freddy Mercury. They share hairstyles, moustache and even attitude. However, Alaindelon is better built being quite muscular. He often wears sweatshirts along with boxer shorts. However, there are also occasions when he wears outfits outside of his daily wear such as the school uniform and a swimsuit (in the anime).

Personality
Alaindelon is a very comical person. Even though he tries to remain serious, his uselessness usually puts him down. He is a dimensional demon capable of going in between dimensions. He also has the ability to open himself up in order for people to enter him and be able to travel alongside him. He also lacks physical strength, but seems to make up for it with incredible durability. Most demons at least make some attempt to conceal their powers while in the human world, but Alaindelon tends to use his transport ability fairly often, splitting himself open even in front of people (which causes a fair amount of shock or disgust).

Plot
He first appears faking his death floating down the river where Oga finds him. Beelzebub popped out of him making Oga his caretaker. Thought dead, he later appears to usually bug Oga and Furuichi. He later goes to live with the latter after finding him a noble person.

Relationships
Angelica

Angelica is his daughter, who makes her first appearance in Chapter 44 of the manga. He is devoted to her, and she him. When he is "dying," he tells the distressed Lamia, Oga, and Furuichi that "he's not going to die here, it's his daughter's birthday and he promised to buy her dresses."

Furuichi

Furuichi is ' weirded out ' by Alaindelon. The latter however, believes Furuichi is "noble" and decides to move in with him so that he can have a home. It's even mentioned that Alaindelon talked to Angelica, his daughter, about him, praising him highly.

Tatsumi Oga

Like Furuichi, Oga generally finds Alaindelon's presence annoying at the least and disturbing at the most. However, Alaindelon's transport ability and eagerness to assist have proven useful to Oga several times. One of Alaindelon's common tasks is to keep Oga informed of the distance between himself and Beelzebub whenever they are separated (in order to avoid the 15 meter limit, which would result in a fatal shock for Oga).

Hilda

Alaindelon assists Hilda by delivering various objects or people for her, and appears to know her very well, sometimes giving voice to the thoughts she is unwilling to share aloud. In particular, he believes that she actually has faith in Oga Tatsumi's ability to raise Beelzebub well, an idea that Hilda almost always rejects.
