Junichi Nagase is known around town as the feared "Geno Killer". One day while out for a walk, he saves a girl from some delinquents trying to cause trouble. That girl was Yuuhi Katagiri. In a fit of impulse, Junichi ends up kissing her, only to find out that because his parents saved her father some time ago, she is now engaged to be his fiancee. Yuuhi then starts living in his house to try and assemble a report on Junichi to prove to her father why they shouldn't be married. The rest of Junichi's class goes to great lengths to tease the couple, so as it goes, Hilarity Ensues.Based on a Visual Novel by feng. A PS2 port with a new voice cast and no sex scenes, Akane-iro ni Somaru Saka Parallel, was released about a year later. Adapted into a Twelve Episode Anime for the Fall 2008 season, and also adapted into a manga.
Ascended Extra: Two ways. Mikoto Tachibana is a side character in previous game of feng, named Aozora no Mieru Oka. On the other hand Minato and her friend Yocchan appear in next game Hoshizora e Kakaru Hashi, and Yocchan is even promoted in incoming fandisk of that game!
Battle Couple: Junichi's parents are almost always seen doing some kind of action movie sequence stuff. His sister also seems to know survival training, although she mentions she spent some years in the jungle with their parents while Junichi stayed home in Japan.
Brother-Sister Incest: Junichi and Minato are teased and accused of this by everybody, though they continually deny it. Much incest ship tease ensues. In the anime, Minato wins. So they were completely right. But what their blood relation is to each other is not clear in the anime, and when you start looking at the games themselves, it gets dicier.
The original PC version, released in late 2007, confirms that they are blood-related.
The all-ages PS2 (from which the anime shares its voice cast with) and PSP versions, however, confirm the opposite. In these two versions, they are Not Blood Siblings.
Butt Monkey: Junichi, although sometimes he borders The Chew Toy due to the fact that he largely doesn't deserve his reputation.
First Girl Wins: But it still depends on the viewpoint. Minato was technically the first girl in his life, but Yuuhi was the first girl we see. So, it's both averted AND played straight at the same time
Parental Abandonment: Apparently Junichi and Minato are used to their parents never being home. However, we do get to see what the parents are doing from time to time, and they at least send Junichi a birthday present for his birthday. And judging from the house they live in, it seems they are at least showing some token support/love for the kids.
In both versions of game, Mitsuki's father is dead, in different situations.
People in Rubber Suits: Karen tries to orchestrate a mock stage show of her versus an octopus monster, which ends up going down in flames. Literally. Yuuhi panicked and set off the fireworks too early.
Porn Stash: Yuuhi discovers Junichi's while snooping around his room. Minato knows all his hiding places, to her surprise.
"Shut Up" Kiss: Yuuhi demands another "first kiss" from Junichi because she felt the first one didn't really count. She then goes on to berate him some more before he does this.
Shrouded in Myth: The legends of Junichi's reign as the "Geno Killer" are still spreading thanks in no part to his friends, who still remember him as that blond-dyed punk back in junior high school rather than the ordinary boy he is today.
