Nosurge ノサージュ, nosaaju?) is the name given to the devices and Songs that interact with our dimension in order to cause a determinate effect. Given their ability to go beyond the Universe of EXA_PICO and establish contact with other dimensions, they are incredibly powerful, but also extremely dangerous to use. So far, the only existing objects that receive this name are the Ar nosurge Tube, and the Cielns Class::CIEL_NOSURGE;, Class::AR_NOSURGE; and Class::EXSPHERE_NOSURGE;.
