You are the commander who got assigned by Syuen to investigate a new sort of corruption virus that has a rather concerning side effect over Nikkes and humans. Your target was a specific mansion where someone worked on said virus in secret. Your job is to sneak inside with your Nikke squad Counters and find out. who Could it be Sixo or someone else?

So far so good. You got in without any issues and head out towards the basement. Rapi and Anis are in front of you while Neon is behind you. You see a lab inside the basement...and in the capsules...you see someone very familiar slumbering... Nihilister. All of you are surprised. As Rapi and Anis check for the computer data on what is going on with Nihilister, someone attacks Neon behind you and injects her with a syringe containing a mysterious substance through her neck. Before you could see who they were they fled. Then you see Neon in pain holding her neck and beginning to convulse. She tries to resist but its no use. Then her green eyes turned pink and black wings appeared on her head followed by a devil tail and her white hair turning red with green extremities and her glasses falling off. She became a literal cyborg demon. Anis and Rapi looked shocked as Neon began running towards them with a crazed look in her eyes. Rapi and Anis try to fend her off but her speed was off the charts. She easily overpowered them both and began infecting Anis with a substance from her mouth. Anis began convulsing and coughing while her hair turned green, yellow horns began appearing on her head and she began emitting an ear piercing scream. That's when Nihilister woke up from her capsule and smashed it to pieces while running towards Rapi to infect her. Despite my attempt to shield Rapi, Nihilister smacked me with one hot across the room. Last thing I saw before losing consciousness was Rapi beginning to choke and having her brown hair turn light blue and pink. They were all infected by the virus. I then wake up surrounded by them looking hungrily at me. I get up on my feet.
