Karmatic Time Trio | [ BCBTU / NTT ] | Phase 2.5 (A) | Unexpected Delaying

[Boundaries Collapse Between Two Universes] After Phase 2, UKB decided to withdraw from the fight along with HM for some reason, and at the same time, Horror decided to help LB and Ainavol to buy some time. Middle of the phase, something went wrong with Ainavol. His eye changed before someone emerged from it: Yukari. Yukari successfully emerged from Ainavol's eye, She decided to try "possessing" LB, and it worked...but not completely. Unaware, LB activated a version of the "bullet train" he shouldn't have been able to use. The "Prototype Phantom Train : Abandoned Station" The surrounding area was enclosed by gaps from which a deserted train sped out, crashing the player, but at the same time nearly hit his friends. But it wasn't long before Yukari was expelled from possessing LB by Gaster, Yukari remained in the battlefield, so she tried using the Gap to bring another Sans here, similar to what happened in KTT normally. However, instead of sending UB, she sent URH(UB×2), causing the KTT code to become unstable. So, it was necessary to stop running URH at 50%, resulting in the UB that appeared being an incomplete URH(UB×1.5). But at least he knew what to do. the end of the phase, Horror is contacted by...Dust? This forces him to withdraw from the fight, and LB is temporarily possessed by Gaster
