After careful consideration, Armin had opted to help out Team Mystic. He was still a fairly new trainer, after all, with only two pokemon. He might get overwhelmed in the fray inside of the tower. Better to let more skilled trainers with more pokemon handle that charge.

(Also Eren because he had charged off before Armin had been able to stop him.)

The streets suited Armin better. He could take down grunts one at a time, rather than get ganged up on. And it was not like securing the streets was without use; there was no way they could retake the tower if Team Skull members were free to keep pouring in from below. Cut off the reinforcements and they'd be able to get rid of them far easier.

Currently, Armin had Amadeus circling overhead, using his keen eyesight to spot any threats before they could gang up on Armin. Juniper the Skrelp was perched on his shoulder, looking a little tired, but still up for the fight.

Rounding a corner, Armin nearly ran smack into Sion. For a moment his eyes went over his odd get-up, before he smiled. "Hello Sion. It's good to finally meet you in person. I wish it was under better circumstances though."
