For those genuinely wondering who the two who died are. Abyss (monster arm girl) and Brown-san (glasses guy) are two of the "Four Revered Saints" that Vysis (bitch goddess) brought in to help train the heroes (the classmates that at least half the people reading this manga whinge about every time they show up).
They (the revered saints) first show up in chapter 34.
Yep. I finally had to write down notes to keep track of the various players. I don’t have notes on hand but will try to recall.
- Imagine a compass. The land of the monsters is in the center, and the various kingdoms are arranged in a circle around it. Most fighting forces belong to one of those kingdoms.
- Goddess is associated with the Kingdom of Albion with is the NE kingdom. However, because of the goddess’ power she also holds huge sway over the other countries. I.e. those other countries are forced into alliance with her/Albion. Relationship is not loyalty or even friendship.
- Four Saints are from Yonato (the NW kindom). They are the leading fighters from Yonato. They aren’t weak. Their getting wrecked is a sign of how strong those monsters are.
- Current fighting is in the north country (Magnar).
- Current monsters are coming from the central monster region (just south of Magnar). Vs demons who are coming from the north. (But perhaps this is N-S pincer movement instigated by the demons.)
- Black dragon knights are from Bakoss (SE kingdom). The black dragon knights we see here are Bakoss' B team. Reminder: the MC wiped out the Black Knights A team including the “world’s strongest man”.
- Neah (also SE) was subjugated by Bakoss about a decade ago. However, they’re not completely subjugated. Cattleya is the princess of Neah, and is leading her own forces. If she does well, then the goddess will support Neah’s return to independence.
- Ulza: Southern kingdom. MC's path went through it. Forces: Monster Slayer Knights. Banewolf is the top fighter of the Monster Slayer Knights (Banewolf is Sougou's mentor, and the guy who just took on giant monster form to fight).
- Mira: SW kingdom. Forces: Band of the Sun.
Generally, the political situation is complex with internal strife between the various kingdoms and Albion + goddess. But they have to work together to fight off periodic invasions from demons. Demonic invasions require the use of heroes from another world to beat the demon king. And the goddess is the only one able to summon the heroes (which is thus a big part of her leverage against other kingdoms).
Likewise the students have their own factions which have different ideals/goals.
- MC: Edgy Hero. Ability: Poison, Parzlyze, etc. (Heading towards N front)
- Sougou: Do gooder, class prez female hero. Ability: None yet. (N front)
- Sougou group: Lower level class members that didn't get into another group. Sougou is protecting them.
- Yasu: Bowlcut nerd/wimp. Ability: Fire. (N front)
- Yasu group: A few likeminded mid level guys. (I think. Don't hear much about them.)
- Ikusaba: cunning gyaru. Ability: ?? (NW front)
- Ikusaba group: Mid level girls group.
- Takao Sisters: Elder sister Hijiri is very cunning. Ability: wind/sound. Younger sister: combat oriented meathead. (The two encountered Eve in central monster area. (NE front)
- Kirihara: super arrogant Ikeman, Ability: Fireball (redirected to NE front along w goddess) (highest power and level (aside from MC))
- Kirihara group: A few mid to high level guys. Don't hear much about them other than Oyamada.
- Oyamada: Delinquent asshole hero. Ability: Bullet. (N Front) Part of Kirihara's group.
ch 46.2 page 3 covers gives some more info there. Also see 47.1 page 2. Kirihara + goddess were originally going to N front, but divert to NE front in 19.1 page 3.
(BTW what I’m calling “N front” is called “S front“ in manga. All of these fronts are on the north central part of the combined kingdoms, but the “N front” is ”south” relative to the center of the invading demon forces.)
