Krile's last chance to shine before she fades into obscurity comes in this Ciaran Event, so I'm giving her a go!
In this fight, it's imperative to bring at least a healer and / or tank to mitigate the sheer amount of HP damage, preferably Basch as your tank as their HP attacks do not rely on doing BRV. As Basch, don't use his 1st skill until the Behemoths finishes buffing themselves, and then you have to make sure Basch has the cover buff starting the 2nd wave. Afterwards, use them everytime they have the red aura.
Krile is doing a lot of work preventing anyone from breaking despite not doing BRV+ at all; this fight only has 2 breaks in total. Krile also helps Yuri deal a ton more BRV damage with "Greater Damage" buff and give a ton of battery most of the time.
Yuri is the DPS of the team with various benefits, allowing everyone to almost always cap overflow, heal up the non-tank damage (the HP poison) while dealing solid consistent damage throughout.
