There were ten people, not including the one who gave them the signal, and they had surrounded Shingi and Himon.
Shingi didn't detect any guards nearby, and nobody else was either.
He noticed that all of his assailants wore the same outfits, designed to hide their characteristics.
There wasn't any symbol on them, but Shingi could tell that they were people from Owl Talon.
He encountered many Criminal Organizations in the past and knew the designs they used for their outfits which they rarely changed.
Shingi cast with the help of four of his Mana Seeds as many Golems as he could, which was eight at that point.
He made them all be Defenders and ordered them to guard Himon and didn't make them appear yet but have them part of the ground until needed. That was a trick he found out he could do during his training at the TRANCE ROOM.
"Stay still, Himon. I will take care of them."[Shingi]
