Part 80

Heartful Cry II (Iori Junpei & Koromaru): Set Metis to Full Assault and cast Thunder Reign on Ken, then let Metis use Akasha Arts to knock him down. This wastes his turn and saves you from his attacks. Ken has Premonition (Dodge all Physical attacks); only Thunder Reign + Shock + Akasha Arts can knock him down. Aki hits critical often if he hits once. He uses Masukunda to lower Ai and Metis' agility. If Aki casts Masukunda, having Personas with Dekunda or Masukukaja can help. After Ken is defeated, switch to Thor (if you used Odin before) and attack Aki with Pierce Attack or Vicious Strike. Ai is not damaged by Aki as long as she's equipped with Thor.

Heartful Cry III (Takeba Yukari & Kirijou Mitsuru): Assign Metis' Target to Koromaru. Koromaru is dangerous with Evil Smile and Ghastly Wail. Masakado with Magarudyne can damage both enemies simultaneously. Cast Marakunda before attacking. If Metis is defeated, do not revive her unless Koromaru is defeated, as she will be downed frequently by Vorpal Blade, Maragidyne, and Mamudoon. With Masakado, Ai is mostly invincible except against Fear. Consider giving Mot's Null Fear to Masakado. Junpei can cast Fire Break on Ai to nullify Blazing Flame's effect, dealing about +150 damage. Attack once or twice before healing with Diarahan. Revive Metis now so she can attack and gain EXP.
