Izaya's Game

Izaya's game, titled ''Fiendishly Hard! Izaya City! Or, a Challenge From Izaya! is a video game created by Izaya Orihara featured in the Nicococo!!'' side story.

Description
As the game was made while Izaya attended Raijin Academy, it is several years old, though Shinra remarks that it works well on new computers. According to Izaya, the game was not very well made.

The entire purpose of the game is to test a player's patience. At first it appears as an ordinary computer game with a male protagonist who can be moved using the left and right keys and the space bar. However, only a few seconds into the game, the character will suddenly fall down a hole. Instead of dying or crashing, the character will keep falling and the player will be unable to interfere. After approximately thirty seconds, a block of text with a new line appearing every five minutes will appear on the screen. The text consists of taunts written by Izaya that Celty describes as "teenager-like" and "pretentious." They at first comment on the fact that the character is falling endlessly and soon blame the player for the protagonist's misfortune. If the player tries to close the game, a new text box will open up, once again full of taunts. This time, it mocks the player for "running away" and admitting defeat to Izaya.

History
Izaya originally made the game in high school and gave the CD to Shinra. Supposedly, he also gave a copy to his sisters. Shinra was able to play for ten seconds before losing interest. He tried leaving it for an hour to see if there was any change, but only discovered that the character fell endlessly.

Shinichi Tsukumoya is the only one known to have finished the game. Afterward, he sent Izaya his honest and harsh criticism, marking their first interaction.

After the events of Durarara!!, Erika enlists Celty to help her in an online rivalry with another cosplayer by making a video and posting it on the site Niconicodouga. Celty attempts to create a Let's Play video using a horror game. However, due to her original choice scaring her, Shinra suggests Izaya's game, describing it as "unknown" and "super hard." Celty plays it for a few minutes before becoming fed up and attempting to shut down the game, only to be taunted again.

Erika and Kururi meet to host a Let's Play live video to make amends for their rivalry. They are joined by Mairu and begin to play the game while Celty frantically types a warning in their comment section, screaming internally.
