I decided to introduce this anime because it's hentai-funny!

ABOUT

Tomoki Sakurai is a perverted teenage boy whose motto is "Peace and quiet are the best," and often has dreams of meeting an angel. He finds it difficult to live in comfort when he has to put up with Sohara Mitsuki, his next-door neighbor with a killer karate chop; Eishiro Sugata, an eccentric pseudo-scientist bent on discovering the "New World"; and Mikako Satsukitane, a sadistic Student Council President. One night, while he was witnessing a strange anomaly in the sky, an UMA (Unidentified Mysterious Animal) crash-lands nearby. Tomoki discovers what fell from the sky is a winged female humanoid named Ikaros from an unknown world of Synapse, who soon declares herself to be Tomoki's servant. From then on, more creatures known as "Angeloids" arrive; with this, he loses his peace and quiet, but at the same time finds pleasant things the Angeloids bring him, and fight the forces that fall upon Earth.　　　　　　　From Wiki

Briefly, the story is all about weird things that happen around a boy named Tomoki.

Hentaily, there's fewer "plots" comparing to the same genre animes, but this anime is surely entertaining

Heroins

Ikaros

The title character of the series, Ikaros is a busty gynoid known as an Angeloid; she falls from the sky at the beginning of the story. After Tomoki recovers her, she forms a bond with him and calls him master: the imprinting is symbolized by a chain from her collar to his hand. She displays a submissive, melancholic and subservient personality, but has shown aggressiveness whenever Tomoki is in danger. She has an expressionless face that makes the other characters wonder if she will ever smile. Her emotions develop slowly, due to her programmed setting of high battle abilities and high processing abilities but low emotional abilities. Despite this, she develops genuine feelings of love for Tomoki. She also goes along with any of his perverted schemes, and eventually burns up into nothing after carrying Tomoki to Synapse, showing him her smile for the first time. She and the others are later resurrected by Tomoki's final wish.

Sohara Mitsuki

Sohara is Tomoki's next door neighbor and childhood friend. She gets annoyed whenever Tomoki acts in a lecherous manner and typically punishes him with a single karate chop. As a child, she was constantly ill and only had Tomoki as a friend. Despite all the punishment she dishes out to him, she secretly loves him, and has embarrassing lustful dreams about him.. She is good at sports, but struggles heavily with English (Spanish in the Funimation dub), and is a deadly cook when it comes to sunny-side up eggs. Eventually, Daedalus reveals that she created Sohara: the girl who died from a childhood illness was Daedalus's original avatar, and the girl who grew up with Tomoki was a clone she made so that he would not forget her

Mikako Satsukitane

Mikako is an upperclassman to Tomoki and Mitsuki and the student body president. She is a childhood friend of Sugata, whom she calls "Ei-kun", and is the daughter of an influential yakuza (greaser) boss in Sorami. She is manipulative, cunning, highly intelligent, athletic, and sadistic. She initiates many schemes in the form of festival competitions that place Tomoki in humiliating situations for her amusement. Unlike Sohara and the Angeloids, she directs her romantic affections towards Sugata, and claims him during the mock wedding in the second anime season finale.
