Ganesha Familia executives. Who knows, maybe they won't participate, but I do believe they are gonna be part of it. And well, we have seen nothing of them really. Even about Shakti we barely know something, so I'd like them to have at least a decent ammount of focus.

Besides that, Allen and the Gulliver brothers.

Mhmm, I know we’ll get to see it but, I want to see in action Lili’s skill Command Call, and see if Haruhime can now at least make 6 tails thanks to her skill and magic progress.

Besides that, Ottar, Ryuu (because of her so called “triumph card”), Allen and the waitresses. And like @Rigel31415 said, if Ganesha Familia participates, get to know more about their top tire adventures.

And maybe Hermes Familia, though aside from Aisha, most probably they won’t participate, they always try to keep this “neutral” facade. But at least I hope Asfi can let them make use of her objects (if magic objects are allowed, though most probably yes, because in the Hestia-Apollo war game magic swords were alright), I don’t know imagine Ryuu using talaria (just a fantasy of mine). But if they do participate, maybe know a bit more about them.

And that would be it, let’s just hope volume 18 will be worth the hype.

I want to see Allen humiliated on the War game because this person deserves it on my opinion along with those two elves.

I have no issue with Ottar there is respect for me towards this character.

Ottar hope he will be there cuz he is litteraly the type of warrior i respect, Allen also mostly for the character development with Anya because he's clearly a hardcore tsundere with his lil'sister and heidin the high elf but him i want to see the guys get ass kicked the most. That will be the character i hope to see in the freya familia. As for the hestia one, i hope Lily and Haruhime will be there, Welf will surely be more apparent as forging one awesome equippement

To be honest, I want to see Allen's sister, Anya team up with others to defeat Allen. I think this is a proper 'ending' to the brother and sister drama. For Hedin, I would like to see Bell lv5 solo him and defeat him. For me, that would a good fight and also an end to the 'master-disciple' relationship. For Ottar, I would welcome Finn, Gareth, Riviria and maybe one more lv6 to battle him out. I think it would be a good achievement for those lv6s to rank up.

Anya teaming up is no far fetched possibility because Allen broke Family ties with her.

I'd love to see Ahnya team up to beat Allen. That would be a great development. Too bad it can't happen in the wargame since she is still a member of Freya familia. She isn't active anymore but she still has a Freya Falna so wouldn't be able to fight against them. Which sucks. Bell beating Hedin is also something that would be great and also likely. Finn, Gareth and Riveria beating Ottar would be cool if it was how the leveled up to 7. Bell would still need to face Ottar at some level though. Maybe he turns the table against Ottar for the others by destroying Ottar's black sword or something. It would also be good to see Welf beat Freya familia's mages with his magic

I personally think Bell will be promoted to level 5 before this war game starts, and then maybe Ais or the Amazon sisters of Loki's family may train Bell to the top of level 5, with all attributes S. As for why I would guess that Ace might not be able to participate in this game. If you consider the rumored situation, Ais owes Freya a favor—Ota used to train Ais.

Game lineup:

All the Hestia Familia, as well as those who are level 4 or higher in the story, should participate.

Let's sort it out:

Hephaestus Familia: Tsubaki Collbrand - lv5

Hostess of Fertility All: Ryuu Lion lv4, Anya Fromel lv4, Chloe Rollo lv4, Lunoire Faust lv4

Hermes Familia: Aisha lv4

I take into account that Haruhime can use Kokonoe to strengthen the level of nine people. That's about as many people as you can count. The current total combat power is still one level lower than that of the Freya Familiar. Most are lv4. In fact, based on strength alone, Freya really wins the game, but there must be some variables here, otherwise the story cannot continue. Bell will definitely fight with master Hedin. I'm more curious, who will Ota fight? Is it Mia?

Another question is what is the gameplay of war games. It used to be a siege battle, but what kind of gameplay is it now?

Bell will play a huge role in how Freya is punished being a softy like he is the boy will forgive everything.

Bell will step in to prevent retaliation because trust me Loki and the others want payback.

Ottar is a powerful adventurer but even him can’t fight all the Familia.
