You need to use Insta-Kill NPs on them, for example Assassin Shiki (single-target), Saber Shiki (provided for the quest, can hit all 3 of them), or any others that you have. Concentrate everything on getting Saber Shiki's NP to 100% or higher, then use her 1st skill to lower their Death resistance (aka insta-kill resistance), use said NP and it's not that hard.
