Sshhh. Princess Syalis is trying to get a good night's sleep. Some shut-eye. Forty winks. Catch some Z's. Long ago in olden times when people and demons lived together in well, disharmony really, a demon king kidnaps a human princess and imprisons her in his castle. Bereft, the princess's subjects, beat their chests in anguish until a hero arises to spearhead "Project Rescue Our Princess". While waiting for her knight in shining armor, what's an imprisoned princess to do? Teddy-bear guards with bat wings are all very well, but her dungeon cell is boring. So, she decides to wile away the long hours by sleeping. Now if only she could get comfortable and didn't suffer from insomnia.

Sekirei

2 Seasons
You've seen a million shows where heroes go toe-to-toe, now feast your eyes only the only anime where hot girls with super powers settle their differences chest-to-chest. Minato had no luck with the ladies until the day a well-rounded warrior babe named Musubi fell into his life and crushed his face with her ginormous cleavage. Hunted by a stunning pair of twin sisters, Musubi was searching for the right guy to give her a squeeze and unlock the hidden powers lurking beneath her ample assets. Minato fit the bill, and now he's caught in the middle of a supernatural slugfest where voluptuous vixens take turns beating each others' clothes off. Only one of these bodacious brawlers will come out on top, but the unbridled excitement of watching them go at it makes this utterly-fulfilling series the breast action-harem anime of all time.

ALL OUT!!

1 Season
Rugby is a sport where anybody can be a star when they hold the ball. The rules are simple: one player has to carry the ball past the goalposts across the field while avoiding the other team, who are allowed to use all their force to knock the enemy down. However, the player can pass to a teammate behind them or kick the ball before they are tackled. Unlike other sports, the game continues even when the person holding the ball is taken down. Kenji Gion is a short but feisty high school freshman at Kanagawa High School. Right after the school's opening ceremony, he meets the tall and timid Sumiaki Iwashimizu, and the two of them get an invitation to observe the rugby club. When Gion watches the match, he realizes that even though big and tall guys have an advantage, there are positions for people of all shapes and sizes. Immediately convinced that he has found a sport he can excel at despite his short stature, he signs up, though Iwashimizu declines. Gion is unable to accept Iwashimizu's excuses and drags him back into the sport. Their training becomes intense as they aim to become the champions of Hanazono, the national high school rugby championships.

Lain's life is turned upside down as she begins to encounter cryptic mysteries one after another. Strange men called the Men in Black begin to appear wherever she goes, asking her questions and somehow knowing more about her than even she herself knows.
