During Nightshift 46, Sechs was put through one of the dreaded M-U sessions held almost nightly at the institute. Six needles were injected into his spine and neck, each of them pumped in a mystery drug that was heavy, cold, cruel and utterly devoid of light. After Sechs' M-U ordeal, he now has the side-effects of the drug to deal with. The dark liquid injected into Sechs' spine reached the dark, negative voice inside his psyche and had given it a terrible life of its own.
The first time Sechs encountered this shadow was when he fought against the Great Whophon in the Z.O.T.T. A master hypnotist who lead a cruel cult consisting of brainwashed members, Whophon used his uncanny powers of suggestion to wreck havoc towards everyone involved with the tournament, even the audience watching the fight. Sechs attempted to attack Whophon but found himself trapped within the hypnotist's illusions. It was then that a shadowy version of himself emerged and tormented him, acting as an outlet for the dark insecurities that festered in the farthest parts of Sechs' mind. Infuriated, Sechs attacked the shadow with his blade but ended up stabbing himself instead.
Nearly identical to the "Dark Side of the Moon" that was summoned by Whophon to torment Sechs, the drug-induced shadow will follow Sechs around and fight to break him down and take control of its host.
Examples of the "Dark Side of the Moon" from BAA Last Order volume 7:
Part 1Part 2[The following effects have been mod-approved]
No one but Sechs can sense the after effects of the drug. It is a psychological menace that will stalk Sechs and cruelly pick away at his weaknesses and insecurities. Despite it not being "real", Sechs' shadow can trick him into hurting himself and others. The fluctuating chill inside Sechs' spine and the constant attacks against his mind and senses will also be a constant hindrance.
The effects involve hearing the shadow's voice which sound exactly like Sechs' own, temporary full or partial disablement of his senses and self-control, chilling temperatures in the back and various illusions of blackened forms including but not limited to Sechs' shadowy doppelganger and a multitude of inky tendrils that surround and coil themselves around their host.
The drug's cold presence inside his spine can be felt by others if they came into physical contact with that part of Sechs' body. Elements of healing that are considered the opposite of darkness can help ease Sechs' ailment, but not cure it.
The side-effects intensify at night and will often be at their worst around midnight. The light of day will bring some relief for Sechs, the drug will lose its intensity and even go dormant during the afternoon, but it won't let Sechs forget about its presence...
UpdateAs of Day 74, (and with mod approval) Sechs' M-U symptoms have been reduced. During his fateful battle with Aigis in the
coliseum, Sechs ran himself through with his blade and expelled most of the sentient poison from his severed spine. With only half of its form still inside its host's body, the M-U's voice is gone and its illusions are greatly weakened. The side-effects such as the unnatural chill and muscle pain remain. Sechs will never be totally free from the drug until it's removed entirely from his spine or he returns to his original body.
