I'm surprised it's Horobi, with Hayate (Jin) you could at least see bits of Jin's armor on the suit. Rui basically has a few matching colors and calls it a day (based on his profile, I guess he just sorta threw some pieces of Horobi's tech together and went back to his game).

Aside from that, the theme with Slam Days seems to be energy/light constructs. Which means their final member might not be who we initially think... I'm still going with Wolf Orphnoch Takumi just cuz the wolf traits and cables on his arm.
