Salinban Mercenary Training Group, Move Out!
Siena and Platoon 17 are disappointed by the fact at how badly they lost against the first platoon in the inter-platoon match. Karyan asks the assistance of Layfon and the Salinvan Guidance Mercenary Gang to move ahead and destroy the contaminoids that the city was about to encounter. Layfon asks for a request and sends a message to Nina. It stated that if she wanted to follow, she was allowed to do so. She declines the option to follow and instead goes out to find Zuellni (the electronic fairy) and see what was wrong with her. Nina goes down into the machinery area and enters an already open door that leads into a chamber with Zuellni trapped inside a crystal and Gandoweria's Fallen One above her. She questions the Fallen One and it simply states that she has an incredibly strong will and it wishes to possess her. Despite Nina refusing it, she was possessed and sent somewhere else. Layfon and the Salinvance Guidance Mercenary Gang ride out towards the Contaminoid nest while being followed by the 17th platoon and Siena (as requested by Layfon). Layfon wishes the 17th platoon to watch and record how the Salinvance Guidance Mercenary Gang fights because he wants to fight with his platoon in the future. Layfon's injuries cause him a few troubles, but he still manages to get the job done. Back in the city, Karyan sends a search team to find Nina and is informed that she simply "disappeared". Layfon, the 17th platoon, and the Salinvance Guidance Mercenary Gang ride back into town (to be informed with Nina's disappearance).
