Threeboot is now slightly more marginally possible than previously.

... I know my mind immediately went to an issekai about four schoolgirls from the Visual Media Research Club taking the excuse of needing to fight the Demon Lord Largo to make their dreams of sleek, stylish mecha-styled power armor into reality with magic to get around those pesky physical laws that make things difficult in our world, from which they (nominally) came. In this version, Mackie is the older sibling, the upperclassman advisor for the club, and most certainly the teen male audience identification character who gets into "hilarious" misunderstood situations with all of them. Archmage "Don't call me Wiz!" Raven is the endearingly quirky old wizard who serves as their instructor by order of the crown, under more or less token irritable protest.

edit: Or, wait, the upperclassman should be Leon, while Mackie is the freshman who just joined! Daley can be a local guy in the new world, maybe the desk attendant for the Adventurer's Guild. Because of course there is one, as well as an MMO style class and level system, at least as interpreted by some sixty-mumble producer who never uses a computer for more than spreadsheets, MyTwitFace, and email, but has heard things from his nephew.
