Confining Immortal Rakshasa in a secluded space? Ever heard of Akabane Kuroudo who had reality manipulation sword that can cut through time and space? Yeah I'd imagine Immortal Rakshasa had the similar power like Divine Providence which allows him to warp reality in some ways that he imagine it to. Props to Maru for thinking this brilliant strategy, but if it is that simple, original Space Rakshasa can just confine every single one of the 8 Guardians without him needing to create an army in the first place.
