1. Seijaku ni Chain-saw 静寂に電気鋸  Chainsou
――The view I'd grown so used to seeing through the lens had been smashed to pieces――
Shinadojima, where two moons hand in the sky.
Every inhabitant of this island, by way of what they call the blessings of the moons, possesses extraordinary powers.
But to make use of these powers requires "compensation", in the form of the sacrifice of whatever the holder treasures most, and so it became natural for the people of the island to avoid utilizing them.
Kou Sekine, the protagonist, is a high school second-year with a great interest in astronomical observation.
In the company of Izumi Iwagami, his childhood friend, and their classmates, he lived a quite ordinary life.
A simple and innocent childhood.
The power a passing fancy drove him to use, the phenomena it caused, and the "compensation" thus required.
From that point begins is a chain of events that will irrevocably change the fate of Kou and all those he knows.
Doujin, but let's take a closer look - what if it's new Indigo. And ... it's not even though there is voicing here (sic!). Characters are normal children overall, just with supernatural abilities. But genre is suspense murder mystery. Each lap takes around three hours, and order of routes is fixed. Not my type of vn.

Hideto appears to be an average guy who works in his parents liquor shop, however, five years ago, he developed a split personality with the other side of him being called “Shuuto”. Shuuto is the opposite to Hideto and is strong and cocky whereas Hideto is quite a reserved character. The only downside to having Shuuto is that he can’t remember anything past 5 years ago. However, he spends his days quite happily with his group of friends. But one day, his childhood friend Nanami moves back after an interval of 5 years and realises that her friend isn’t the same as he was and gets suspicious. As Hideto’s second term at school starts, will he be able to keep his split personalities a secret?
Setting is somewhat intriguing, but realization is rough with SOL scenes suffering the most. Common route tries to present comedy while individual routes are plain serious. There is no twist, so it's just not exciting.

6. Doushite Daite Kurenai no!? ~Onna no Ko Datte Yaritai no!~ どうして抱いてくれないのっ!?～女の子だってヤりたいの！～  Chococo 1 2
Haruto loves girls a bit too much and confesses to them indiscriminately, ending up being rejected every day (the count is up to 665 now). One day, a cute girl transferred into his class and he quickly went to confess to her. The girl Misuzu responded with a question: “Do you want to make a girlfriend? To find love? Or maybe only to have sex?” Caught off-guard, he stutters that he might want a girlfriend. Hearing his answer, she smiled and cast a magic spell on him making him popular amongst girls. He didn’t believe it at first, but when girls he had never met before started confessing to him, he found himself in heaven. That is until she told him that the spell will wear off as soon as he has had sex with a girl and that girl will forget about him.
There is an English impression which supports my thought that nothing good can come out of pheromone type of concept
Atsushi and Miyu are childhood friends who are known as the perfect couple by friends and family. They’ve been together since they were small, live next to each other, and are often teased by others for acting like newlyweds. However, there’s one big problem. They’ve never properly confessed to each other. Even though they are so lovey-dovey, it is too embarrassing for them to say those few words, believing that they do not have to say it because they know it deep down. However, Miyu wants to one day have the courage to say the words “I love you”.

Eight months have passed since last Abel Software game, so there must be quality improvement. But no, there's no opening, no voicing, game story is short. Plus, there is this detective hyperlink system, so there is constant need to click at the pink hyperlink words to fill in glossary. Moreover, there is also zapping system, and game gives try again endings all the time without abusing it. All that makes capture absolutely irritating or infuriating just to cover game's lack of length.
