After rereading this from the beginning, I have to say, I have mad respect for the author. This is such a fluffy story that it can go unnoticed but there is some REAL intricate work put into the plot here. Every arc and every character is a carefully placed piece that has broad impact, even the ones that seem like filler. One might be tricked into thinking only the school arcs are real story, and the off-school arcs are filler breather arcs, but taking everything together, its not like that at all. This story is obviously leading towards an eventual grand reveal of Iruma as a human, and while the school arcs are the carpet in which that plot develops, the off-school arcs are the building blocks that are being set for the grand finale. This is not spoilers, just my opinion, but during the series climax the author will most likely present to the demons the idea that Iruma should still be a part of the Netherworld (and maybe even demon king) DESPITE being human, and that's where the filler arcs will come to into play because each one has been meant to establish his influence in a different important sector of the demon population outside of the micro cosmos of school. The Walter Park arc put one of the richest and most influential demons in his debt. The Evidols and Evidol Games arcs put an entire sector of very influential demons on his side. The Many Ears arc again, another sector of demons that will become influential and be his allies, independent from the people of Babyls. The Balam in Levialon arc let us know that Baal's movement is much more widespread than his little close-knit group, and the little single episodes in between and the Goetia Museum arc let us know that the misfits are not just regular demons that happen to be talented, but rather they come from incredibly badass families that can all logically vie for places in the 13th crowns: Azmodeus ofc, but Sabro's uncle is a 13th crown, both Lied and Jazz have 8th rank siblings when you need to be 9th rank to qualify for 13th crown, Kamui comes from a bloodline tied directly to the throne, Kerori is an influential devidol, Purson comes from a distinguished spy family (whose missing brother is probably part of Baal's group), Gaap has a bloodline ability that can drive demons crazy just by showing his face, Allocer is chummy with important and influential academics. All of these people are being set up to be Iruma's suport for his eventual grand reveal and they were almost all set up through "filler arcs". Truly I was a fan before but now I have incredible respect for what the author has set up to accomplish here
