Principles
Designers' Gel is an artificially redesigned fat which can change shape and rearrange the structure of cholesterol. When inserted in human body, it can cause the completation of a thrombus in about a week even with its amount carefully adjusted. Even if there isn't enough data, it is believed to possibly be an excellent assassination weapon that would slip past any forensic investigation. The Designers' Gel's shapeshifting properties are employed in the costruction of the FIVE_Over (Out_Sider) - Modelcase_"MENTAL_OUT"'s base unit, a wearable weapon resembling a cream-colored octopus taller than a person with tentacles extending from its bottom half.
