V.

Unlock Requirement

Level Easy, Hard and Chaos: Paff , NEKO#ΦωΦ and ROBO_Head reaches Lv.56, Ivy reaches Lv.30 and open the file "Main_Log_702_10_25".

The artist "Æsir" is actually a collaboration between Ice and KIVΛ.
This is the longest song in Cytus II, beating the last Æsir song CHAOS by 16 seconds.
Like CHAOS, the first half of the song is a remix of Cytus songs. Also, CHAOS can be heard throughout the song.
These songs from Cytus can be heard:
- Bloody Purity (Chapter 6)
- Quantum Labyrinth (Chapter 7)
- Masquerade (Chapter 8)
- To Further Dream (Chapter 9)
- Halloween Party (Chapter 10)
Welcome to Cytus II (Main theme before opening the post "iM System Æsir-FEST corrupted data recovery progress......100% ") can also be heard.
This is one song in the game where all the difficulties are maxed (Easy 6, Hard 10 and Chaos 15)
- The only other song like this is Floor of Lava.

This may be the hardest free song of the game.
Due to the stop and sudden rapid scan line movements before the drop, it has the fastest and slowest scan line BPM in the game, going to ∞ BPM (teleporting scan line) and 0 BPM (stopping scan line) respectively.
In the Easy and Chaos chart, a set of drag notes shaped like an inverted and a normal "V" letter can be seen respectively, referencing the title "V.".
A segment of bit crushed speech can be heard before the first drop. From the "Welcome_to_cyTus" event, it says "wake up".
A version where the song was run through a bit crusher is used when NEKO#ΦωΦ, Paff and ROBO Head reaches Lv.55 then open the empty post by Xenon.
- This version features sudden rapid scan line movements, similar to the ones in Brain Power.
- After the first V. story chart has been completed for the first time, the iM becomes unusably glitched until the unlock requirements for this song are fulfilled and the second of this song’s story charts is completed.
In the Rayark's Cytus II TW Battle competition held in Taiwan, this song was played in the final round before it was released.
