Gundam, QB, and My Contract: Building a Harem in UC

#A cheat-based contract, with a few harem heroines from non-Gundam worlds. A pure UC Newtype story following the Deikunist path. Otherwise, there's no way a single transmigrator could sort out this UC cesspool.#

Luther, an older otaku from the Magic City, was obsessed with the old game Gihren's Greed. By chance, he made a contract with this world's QB, who was trying to change the timeline of a parallel world to gain energy. The parallel world Luther chose was the Universal Century (UC) of the original Gundam. Besides Luther himself, QB, who was "well-versed in human nature," also offered him a cut of the profits. As long as Luther made enough progress changing the timeline, he'd get a chance to recruit helpers from other parallel worlds, making it easier to snowball his way to victory. And since Luther even chose a "wish for QB" miracle when making his contract, much like in Ah! My Goddess, of course he'd pick his helpers from among his "wives"!
