Persona 3 FES The Answer Rebellious Cyclops & Acheron Seekers (2 Members Only)

Arguably, the most annoying Guardian-Type enemy in The Answer.
The Cyclops can hit pretty hard with physical attacks however since it takes normal damage from physical attacks, an Attack Mirror when it Power Charges can take down a good chunk of its HP. It also takes 125% damage from Elec attacks on top of that.
The main threat/annoyance comes from the Acheron Seekers, they have decent Agility Stats to backup their Evade passive for both of their Fire & Elec weaknesses. They only take 25% damage from Slash, Strike, and Pierce attacks making physical spamming an inefficient way to do any significant damage to them. Mostly importantly, they are programmed to relentlessly target any Instant Death weakness, so Ken & Koromaru are a sure fire way to give the Seekers 'One Mores' unless an accessory is given to cover their respective weaknesses.
The only saving grace is that all the enemies here only resist Poison and the 'Assign Target' AI bug.
Virus Breath can be used as an opening move to cut down all the enemies on the field by 25%.
Use Assign Target with Koromaru, so he will use Maragidyne on the enemies due to the Assign Target AI bug. Adjust the Tactic for Koromaru to Knock Down, if there is a free-turn for Aigis to use Maragidyne, else leave the Tactic on Assign Target so Koromaru can damage all enemies on the field.
This will be a play-through of Persona 3 FES The Answer(commonly known as most boss encounters that have weaknesses will have Dodge/Evade passive to counter those weaknesses) while using only two members as a restriction.

This is the hardest boss in all Persona 3, excluding the superboss, IMO. Great job!
