"Greetings to the Green Messenger!", The three of them bowed suddenly,
Rex steps back in surprise when he saw the three suddenly bowed in a union, even their faces can't be seen as they bow deeply with respect.
Hearing this, Rex glance to the side and finds thankfully no one near.
The students are a bit far from where they are so they shouldn't be able to hear what the three said, it makes Rex sigh before he looks back at the three, "What are you doing?"
"We're here to officially greet you for the first time", one of them replied.
Upon closer inspection, Rex finds that the two guys in front of him are twins.
While the other guy that has an indifferent but slightly shaken look is the strongest amongst the three, it's clear that the three of them are from the SCO.
The twin with a short brown hair then said, "We're giving the messenger the respect they due"
