Damn, Mr. T really fell on tough times after the A-Team dissolved. And it's funny how they keep talking about delinquents and delinquency when they've all already stepped into full-fledged gang warfare with intent to murder.
I wonder what the best course of action would be. Yoshiki might've promised to help this gang out in exchange for helping them destroy rival gangs, because simple protection wouldn't amount to much, since Kyoranki could freely move out of the scrapyard once Kilihito was conquered. What can Kilihito offer then? With Kilihito intact, the situation in the area would be more chaotic, since they've worse relations with the other gangs. If the other scrapyard gangs are also affiliated with other Japanese gangs, then it could help these foreigners if the Japanese gangs are at war, since it would make it harder for the the other Japanese gangs to reinforce their foreign allies, plus the police would be more busy with the Japanese gangs and have less time to go after the foreign gangs lurking in the periphery. Kilihito could provide a better stage for these foreigners to expand.
Also, if Kyoranki amasses too much territory and power, it could mean they'd stop supporting their scrapyard allies, as they'd no longer need their support. Yoshiki is, after all, a traitor within him own gang, and a traitor can keep betraying, as Kai himself said. This foreigner boss obviously doesn't give a fuck about what kind of asshole Jousuke was, so he likely won't be very understanding of Yoshiki's reasons. Meanwhile, Taguchi is going to this length just to redeem himself, and Shou betrayed Kyoranki for Kilhito as well. In terms of who'd be a more loyal ally, isn't Kilihito the better choice? According to the Japanese gangs, Kilihito went too far by turning on their seniors, but that's just discrimination based on how everyone feared Jousuke, as Yoshiki and current Kyoranki were the ones who turned on their seniors first, so if you look at it from an unbiased perspective, Kilihito are the loyalists and Kyoranki the rebels.
