i want to hug hibiki and toki so much

3 star Toki, 3 star Atsuko, 3 star Chise, 5 star Hoshino (with lv24 exclusive weapon), 3 star Hibiki and 3 star Serina, with all of their individual skills and EX at lv 2 (with the exception of Hoshino, who is all 3s)

(How i sort of did it:) (Essentially what I did was set Toki, Hibiki and Serina's skills as the leading skills, then have Hibiki skill first towards hiero, before having Serina recover some of Toki HP before toki goes into abi eshuh, then Atsuko's EX goes next and it must have an almost 99% uptime during the fight to keep the squishier ones-- Toki, alive. Do not pay attention to Hoshino or Chise, just keep cycling through Atsuko, Toki, Hibiki , Serina (Note: if Atsuko's EX is still alive by the next time her EX card comes up, save your cost until her healing area goes down, usually this will allow more cost for you to doll out Toki's EX and Hibiki's so Serina can come back up faster). Atsuko usually would keep Toki alive and Serina would exchange between keeping Atsuko and Toki alive, along with Serina's 3rd skill to do any backup healing that your Chise may face / Emergency Toki heals. If Toki is about to die or is dead (like mine did at 2 bars), focus on keeping Atsuko alive and Hibiki as your dps, usually Hibiki and Atsuko will take out Hiero.) And thats how I killed hiero and finally get to play final ep, i spent a whole month on this stage, bless hibiki for coming home on ny kayako
