Strategy
MP Drain strategy is highly recommended as it has the benefit of denying the use of Zero Shift, which has a high potential to end the fight. The basics of the super bosses apply, but there are a few things one should keep in mind: Check here and here for detailed information on all the super bosses and everything you can make use of to defeat them.
 * Holy Martyr and other such skills will not activate during Time Stop.
 * Skills that can activate at the end of turn from characters such as Naia (100%), Mimi (33%), Pochi (33%) and Panty Sensei (25%) immediately interrupt Time Stop.
 * Ongoing skills that have an effect at the end of the turn (Request Reinforcements) can also use up some of the turns of Time Stop. 1 if one person, 2 if more.
 * Zero Universe doing 9 hits means it can very likely end up killing someone even with multiple layers of Vicarious Clara so keep up enough to make that unlikely.

Battles against her with only Part 1 equipment, no Crisis Hairpin and no stats upgraded without Vicarious Clara and with it.
