Video made to clear the challenge quest in 3 turns.
Take in mind that RNG can screw up and make it so you need 4-5 tuns instead of 3.
Poster Girl can be replace with any CE that gives target Focus as long as it doesnt have something like invincibility or damage cut, if the focus CE is level 1 its better.
golden captures the carp can be replaced with any other CE that grants a buff when entering the field. i chose it because i wanted to crit as much as possible for Dantes to gain more NP gauge.
And for the last tip, before using the NP to break the 2nd bar on turn 2; make sure to stun Shuten, as she can trigger a skill that seals the NP on Dantes, completely ruining the strat. i didnt stun her because i forgot that, but rng was on my side and she didnt seal him. lol
Hope this can be useful to you.
