The next arc better be Mr. Henri reporting, Ameri, and the love trio sneaking into the human world, to find Merize. OR I SWEAR TO FURCKIGNG GOD!!!!! Iruma can go through the gate and with Ali-san's help literally summon all of them. We don't know how deals work yet but I bet there could be like a loan system. Cause Sully is obvs onboard so Iruma owns his for a bit loans it out to the group summon for help finding Merize. Then human-world road-trip (plus little maiming, and traumatizing iruma's parents on the way. Without him knowing of course). If body parts need to be exchanged for deals well has been getting a little chubby lately haha jk jk. But like hair is technically a body part nails too. Hair and nail clippings easiest least harmless parts to give. And well it Iruma so even if he needs to offer blood. Our boy would hand over a few drops no prob. So boom like I said human-world ADVENTURE/RESCUE/AMERI ALMOST DIES DISCOCIVING AMINE BEGINS! They find Merize who has been waiting for dummy husband all this time. Reunion, tears. Since Iruma is alive and actually thriving in the netherworld it turns out Sully found out a way to protect a human from the tough environment through blah blah magic bullshit. But Merize can come back. End of the arc is Henri and Merize making a deal her soul for staying by his side. The groups deal with Iruma has been fulfilled making a portal to the netherworld appear. And they all go back home. Final panel is Henri, Merize, and Ameri walking through wind in hair, with smiles on their faces. Finally going home as family for the first time.
