Clear the waves of minions using spells they are weak against

Your main target isn’t really Mammon but his lackeys. The first wave is weak against Fire attacks and Wind Attacks. If you have Hell Biker who’s armed with Maragi then, it’ll be helpful. The next set is purely Wind skills so having Morgana or a persona with wind skills is a good idea. The next set is a test of Psi/Agi skills. If you have Haru Okumura, have her cast Mapsio or any of her psi attacks. After that, load the two blue lackeys in the middle with fire attacks.


The next set has three golden lackeys and one lanky, tall one. The tall lanky one is weak to Nuclear attacks so if you have Makoto, that works. And the last three, take them out using Haru’s Psi skills. The next, you have four tall and lanky lackeys with three red ones and one blue. The red lackeys are weak against Nuclear and Electricity and the Blue on weak against Wind. Next set has two large green lackeys and two blue lanky ones. The two large green lackeys can be shoved off with Psi attacks and two blue lanky lackeys lose out against Wind skills.

Look after your HP and cast debuffs on the boss

After he sends a wave at you, Kunikazu Okumura decides to send Execurobo MDL-ED, a massive black robot that dons a formal suit. It doesn’t have any known weaknesses so just do the usual maintain HP. If you have debuff spells, it could help speed up the fight. Spells such as Rakunda and Matarukaja will definitely help in defeating the boss. However, do watch out for its Charge spell. It can hit you hard if you’re not careful. Also, if you have Hunger – it’ll save you from its Big Bang Challenge attack.

Once you defeat the large black shadow, you finally get to put down Kunikazu Okumura. But he’s not that hard. Keep whittling him down to finish the palace.
