Teacher instructs the class that at summer vacation textbooks are prohibited and only erotic journals are ok to read. And then he visits students at various locations to check if they follow instructions properly.
Game is made like a parody, but things go ecchi very fast.
2. Manami ~Ai to Koukan no Hibi~ 真奈美 ～愛と交換の日々～  Red Zone

The most weird thing in the game is that Manami whose name is in the title does not have much action during the game after the opening sequence. The focus is on her partner and different swinger club wives.
3. Trouble Chaser Dai 4 Wa - Saishuukai トラぶるＣＨＡＳＥＲ 第４話 最終回  Nihon Create
In the final episode Daisuke gets kidnapped and it's revealed why he's been hunted for this whole time.
All the mysteries get uncovered and we get to look at villain point of view. There's of course a grand battle involved. Since 3rd episode of the game is a lost piece we also meet some new girl pilot for the first time here.
Majo-gari means "witch-hunt"; indeed, that is the only thing the protagonist of the game, a young priest living in an unspecified European-like town, thinks about. According to his own words, he believes neither in God nor in the devil; his life is dedicated to one horrifying passion: torturing innocent women...
There is an English review.

A fighting girl transfers to a girls school. Rules and student council are very strict there. After the girl refuses to dress normally and give away her gloves and kneel-pads the student council kidnaps her roommate.
There are several endings with some being bad ones. The aim is to go around the school, trigger events and beat enemies which leads to les scenes. The overall playtime and the number of CG are small.

One of the most hated VN creators Giga makes it appearance on the visual novel scene! But they are praised for action game and their first game is actually an action, or rather a platformer. There's a good English review for this game.
Charade describes the daily high-school routine of a girl named Kazumi. The game proceeds from one school day to another, putting Kazumi in the same situations, facing the same choices. Those choices, as well as random events and meetings with other characters, schoolmates and teachers (only female), change Kazumi's viewpoints as well as relationships with the other girls.
Yuri school ADV. The weirdness of this game is that you set the setting yourself, like this girl will be in the theater and arts clubs and we'll start to pay her attention. And at any time in the morning we can choose - forget it all and get a new setting. Characters aren't cute enough to empathize as well. Game is fully voiced, but making a setting yourself and participating in constant loops just in hope to find an action that would lead to some branching is not the most exciting occupation if you're expecting a story to be told.
10. Leap Toki ni Sarawareta Shoujo ＬＥＡＰ 時にさらわれた少女  Ange
Hero has finally confessed and made love to his childhood friend Ai. But as he wakes up in unfamiliar place, he can't find Ai anywhere. He begins his search.
Hero needs to travel through the time by having sex with school nurse and find traces of Ai in different time segments. There are multiple endings depending on whether he chooses some local girl or keep on his search. There are a lot of selections and branches in addiction to already confusing time travel. It's an experimental work with a lot of edges, oh well, and it's not hookable.
Tetsuya is a rather ordinary Japanese teenager, who prefers hanging out with his sweetheart Rika than going to school. His passion are 3D video games. The newest game machine which allows the player to completely submerge into the virtual world, modeled according to his desires, has captured his heart. But one thing is strange: lately, Tetsuya keeps seeing himself as a killer and rapist. Dreams begin to haunt him. Is this just a side-effect of the game, or does he have a dark side he knows nothing about? Or maybe the game took him to another world, which will from now on become part of his life?..
Quite an unusual mix of genres and with animated scenes on top of that. The first work of the company we all know as Jellyfish for being the only ardent adept of fully animated eroge. A merry game, but not hookable and rather short.
