4 fighter and 1 level 50 healer would be recommended for quick and easy clearing.

Recommended Units: Trystan, Selene, Ryubia, Angelica, Lynda, Elda, etc

Recommended Healer: Melvina (Removing Poison and great heals)

If you're lazy, just use any strong units you have that is level 45 or higher or if they're 4* / 5* then any level above 30 would do since stats are decent enough to clear it (unless it's Selene). Though if you already have like a level 50+ Haruaki, capped  MLB Lynda, a Ryubia level 50+ then a 5* that's level 15 and say it's Trystan then it's fine enough to use him too. But mainly if your party consists of fighter arcanas that reached either their non-LB level cap or already maxed level on any LB then use them.

My party consist of:: Selene (75), Ryubia (52), Haruaki (60), Melvina (51); my sub-party has Zaren and Haruka as fillers for leveling purposes for the next demon raid.

I don't use my Trystan since he is low level and that I have a large amount of friends that uses him as lead. You just need to know how to roll your mana each wave but more likely that at the start of each wave if your units has HP recovery skills like mines, you will have no issue with survivability by just auto-battling the quest even at each boss waves too since you only need to go normal speed to time your specials and chaining skills.

@commenter above me:

Periodical Heal is good but a heal that provides substantial amount will be the better option due to Boss Waves. If your party is strong enough, Melvina's heal with antidote properties will suffice since poison is worst than the bombs. As for the second Zaren (archer), he has low HP and is very easy if you just hit him with brute force using fighters and counter him with a daze attack. For me, he dies before using a special.
