IM System

The iM system is the social media platform in Cytus II. It serves as the game's story progression and the method for unlocking new songs. By playing songs, the characters will gain XP and level up.

• When the game released with version 1.0, the level cap was 25. These level caps were eventually raised as the game updated with more content.
• In the 2.0 update, Ivy became the first character to have an initial level cap of 30.
• Update 2.3.9 released Miku, who is the only character who has a level cap of less than 20.
• In update 2.8, Sagar and Rin were released, though their initial level caps were 20.
• In update 3.0, Vanessa was released with the original level cap of 25.

Personal OS Logs also exist for each character, and convey other key story events.

Gaining XP

After playing a song, that song's character gains XP based on the score achieved:

XP gain = 150 * (score / 1,000,000) + Bonuses

Bonuses are awarded as follows:

• Completing a song's difficulty for the first time: 100 XP.
• Achieving a Full Combo (50 XP for the first FC of that difficulty, 25 XP afterward).
• Achieving a Million Master (50 XP for the first FC of that difficulty, 25 XP afterward).
• Completing a song whilst a character is level 25 or above will reward an additional 100 XP.

Story Progression

When a character gains enough XP to level up, new posts may appear in the iM feed, which acts as the game's story system. Often they'll be from the character who leveled up but can also include other characters and NPCs. Posts have a like button that can be pressed (however this will only affect the number of likes through the whole server), and a comment section, where additional story elements can be found.

Level Locking

At certain points in the game, a post will be locked, and can only be unlocked when the specified characters reach a certain level. When a character reaches the desired level, their level will be locked. That character can then no longer gain XP until the locked post is unlocked and opened. This serves to make sure each character progresses at the same pace.
