After Eva sent the message to deploy the core members, the evil loli smiled widely and cruelly. She had kept their participation to a minimum in order to get a feel for the battle and allow the non-core members to rack up some kills.
Everyone in Umbra was at Rank 2 and quite a few had Classed Up into Rare, Semi-Epic, and Epic Classes, so with the x4 overall boost from Hikari's White Light Blessing they were literally bulldozing through the void monsters so badly that they began to flee at the mere sight of a human with the badge of Umbra. As one could expect, none of Umbra's members had died yet.
However, the same could not be said for the members of Meiren, Kamisuo, and Desecrators. Around 10% – all of which had been basic members – had already moved onto the shadow realm, without getting revived by Hikari for obvious reasons. Nevertheless, the ones still alive found it hard to join their comrades with Hikari's White Light Healing focused on them.
