Codex Gamicus

CROSS†CHANNEL is an eroge for the Windows and PlayStation 2 platforms. The Windows version was released on September 26, 2003, and the PS2 version (CROSS†CHANNEL~to all people~) on March 18, 2004.


Gunjo Gakuen (Deep Blue School) is a facility designed to gather and isolate those students who got a high score on an adaptation exam (Scoring high on this exam indicates that the student is less likely to be able to be adapted to the society) mandated by the government.

After a failed summer vacation with other members of the school's broadcasting club, Taichi and some other club members return to the city, only to find that all living creatures within it except for the club members have completely vanished. In order to confirm the status of the outside world, Taichi decides to gather other club members to help Misato Miyasumi, the president of broadcasting club, who is trying to set up a broadcasting antenna to contact any possible survivors. However, Taichi soon discovers that the world is actually repeating the week after they found the others vanished…

Main Characters[]

  • Taichi Kurosu: the protagonist. He calls himself "Hentai the Great". He was trying to act as a human while hiding his score of 80+ points on the exam, which is almost beyond human boundaries.
  • Miki Yamanobe: a girl with a cheerful character and small breasts.
  • Kiri Sakura (Sakura is a family name): a squeamish girl who does not like Taichi. She is a good friend of Miki.
  • Misato Miyasumi: a girl with glasses and large breasts. She is the president of the broadcasting club. She scored 30+ on the exam, which is unusually high.
  • Touko Kirihara: a girl descended from Samurai. She used to be intimate with Taichi, but is now very harsh to him. "Kirihara" is an anagram of Harakiri.
  • Youko Hasekura: a girl Ninja. She's always monitoring Taichi.
  • Nanaka: a mysterious girl who wears a school uniform different from that of Gunjo Gakuen. She always suddenly appears or disappears in front of Taichi without warning.

Nanaca Crash!![]

Nanaca Crash!! (actually spelled NANACA†CRASH!!) is an online spinoff game featuring characters from Cross Channel. The object of the game is to click, hold and release the mouse button to determine the angle and velocity of Nanaka crashing her bicycle towards Taichi, sending him flying across the screen. Your score is determined by the distance of his flight. Certain characters he crashes into will greatly affect his velocity. It's now also available for iOS and Android with additional features.
