"The most dangerous. You should devote as much concentration and attention as possible to this Risk Level. You’ll be thankful if the Abnormality is suppressed without ravaging entire departments. (Please do not take our warning as an exaggeration.)"
- Manual
ALEPH Abnormalities are extremely dangerous both in containment and when they trigger their abilities, being more dangerous than 
WAW Abnormalities. Their abilities are the most powerful in-game, as well as having unique styles; from transformations, massive area damage, to the summoning of minions. Abnormalities of this class are able to cause a 'Game Over' if they aren't suppressed in time or are left unattended.
Just like WAW Abnormalities, working with these Abnormalities will trigger a special effect called Qliphoth Overload that decreases 
Success Rate with the Abnormality by -6% after each work (with a maximum of -30% penalty). This effect remains until the next level of 
Qliphoth Meltdown is obtained.
When finishing a day with an ALEPH still breaching, no LOB Points will be gained from that day. A warning will be shown along the button to end the day when all energy is collected.

Summaries[]
1. Nothing There will steal the body of its employee when getting a bad work result and must be suppressed with a special disposal mode before truly breaching. It can be suppressed but this is extremely difficult when it reaches its last form.
2. The Silent Orchestra will increase its damage output overtime while breaching, changing its immunity constantly. It is also difficult to keep in containment, due to its mood mechanic. If its suppression cannot be done in time, it will deplete all energy collected.
3. WhiteNight transforms blessed employees into Apostles. The player can not Pause or change the Speed or escape as long as WhiteNight is breached. You will obtain the "unobtainable" when you suppressed it by force.
4. Apocalypse Bird will appear as soon as the three birds (Punishing Bird, Big Bird, and Judgement Bird) enter an Abnormality called Entrance To The Black Forest. You will not be able to pause, change the speed of time flowing, or press ESC when a certain egg is not suppressed yet. You will obtain the "unobtainable" EGO gifts when you suppress it.
5. The Mountain of Smiling Bodies can be suppressed easily at first. However, after it consumes a certain number of corpses it will grow in size, developing deadlier attacks.
6. CENSORED instantly makes any employee below Level V panic. It can restore its 
Health by consuming the corpses of employees, creating minions soon after. Level V will be Hopeless by losing 60% of their maximum sanity.
7. Blue Star inflicts strong White Damage throughout the entire facility, instantly killing and panicking low-leveled employees, absorbing them after.
8. Army In Black disguises itself as a ZAYIN Abnormality, but when breached it reveals its true classification through dividing into four ALEPH Risk Level imitations of its own.
9. Melting Love can spread its infection quickly, breaches upon converting half of the facility's employees into its minions.
Trivia[]
ALEPH is based from the Hebrew alphabet, the 1st letter, Alef (א). It represents 'master' or 'Lord.'- ALEPH has the least amount of Abnormalities out of all the Risk Levels.
- It is the only Risk Level with no Tool Abnormalities.
- ALEPH is the only Risk Level to lack an “F” classification code Abnormality in the game.
