Expulsion

Expulsion (stylized as eXpulsion) is an organization of fighters. It's the actual primary organization of citizens who wish to rise against the Tekiyoku, being formed before its ally organization, the Mokusetsu, but not before the Kasai Militia. It currently operates mainly from its headquarters in Unova. Its leader is unknown.

Formation
After Alain left the Tekiyoku, he occasionally traveled to Unova. There, he spoke to a man he knew about how he'd be gathering Arceus's Plates after they stop being dormant. This motivated the man to gather like-minded people who desire to put an end to the reign of the Tekiyoku, since there was finally a way to do this with Manipulation. The man and Alain agreed that the latter would guide these people to Plates, while, in the meantime, the man would help train these people to be skilled fighters, making the added Manipulations later complete their skillset for a war. This group was then formed with a few recruits, being named eXpulsion.

However, after this group was formed, Alain changed his mind, saying he didn't wish to be part of another organization after everything that had happened with the Tekiyoku. He also said a reason was because Arceus had only told him to meet up with Ash. Before that, Alain was going to bring Ash to eXpulsion, but he decided that it'd already be tough to enlist Ash's help, given he hadn't met him yet. Alain told the man he'd go about this on his own and opted not to be part of eXpulsion's operations.

Despite this, the man continued to run eXpulsion and recruit more members. Training took place in its headquarters to make its fighters stronger. Since they didn't possess Plates, no one was a Manipulator; it's possible the man continued with eXpulsion in case Alain changed his mind or at least brought Plates to the organization to make some of its members Manipulators. Without Manipulation, it's likely that eXpulsion's fighters wouldn't stand a chance against the Tekiyoku.

Recruitment and Training
Not much is known about the recruitment process. eXpulsion is secretive; most of the world hasn't heard of it. The Tekiyoku is aware of them, but it's not known when they learned about their existence. The Tekiyoku doesn't even mention eXpulsion often, at least not in their transmissions to the world.

It's likely that recruitment is done by word of mouth, meaning you'd probably need to know someone who's in it to be aware of the group. The leader could've reached out to people whom he was familiar with in the beginnings.

It's been mentioned that training is rigorous. The leader is said to be even stricter than Alain, having an intense program meant to make members as strong as they can be. People in eXpulsion don't have too much time for other things. With the organization being headquartered in Unova, members who live far from the base, or who aren't even from Unova, likely live in the headquarters.

Operations and Membership
Day-to-day operations of eXpulsion are unknown, other than traninig its members in fighting.

Clearly, members of eXpulsion aren't allowed to be in the Tekiyoku, but it's fine for members to be in both eXpulsion and the Mokusetsu, although having time for both would be a challenge.

Present
eXpulsion hasn't made a large presence in Tears of the Fallen yet. It's only been talked about so far mainly by Alain. It was first mentioned (not by name yet) during a secretive conversation between Alain and Kiawe in Episode 33. During more similar conversations in the next few episodes, it's shown that Kiawe wishes to join the organization, somewhat concerning Alain, although he didn't forbid it. Kiawe was keeping this a secret from his Alolan friends and had only told his mother and father at that point.

eXpulsion's full name was revealed in Episode 36. Alain and Kiawe were done keeping this a secret and explained the organization to the rest of Division A and traveling companions in Alola at the time. Alain talked about how it was formed, but didn't mention who the leader was. Kiawe's friends were shocked at him wishing to join eXpulsion, but ended up supporting whatever he decided to do, even being okay if he was a member of both eXpulsion and the Mokusetsu.

Trivia

 * eXpulsion is named from the fact that "expulsion" is the noun form of "expel"; one of expel's definitions is to force someone to leave a place. The idea is that these people wish to force the Tekiyoku to leave from its control over the regions.
