@Nevos definitely magic, but magitech, kinda like in City of the Dead Sorcerer or actually maybe more like a combination of UQ Holder's magic phone and Mahou Sensei Negima's partner-card's severely underappreciated outfit storage ability
*for those who don't know, Negima has conditional time travel and it's quasi-sequel UQ is based in the same multiverse, approx. 80 years after the end of Negima, set in a version of the "bad ending" timeline from near the end of Negima*
