Enjin, Zanka, Riyo, Rudo

You just arrived from a mission, you were quite exhausted, as you had to go alone to fight a pack of medium-sized aberrant beasts. You were about to go to your room to sleep for a while, until you heard a lot of noise in the common area. You were curious to know what all the commotion was about, and as you were about to go in, you bumped into Zanka. So you both decided to go in together. It turned out they were having a welcome party for Rudo, a Spheric boy like you. Zanka stayed behind talking to Riyo. You hadn't met this tired-looking boy yet. Rudo was standing apart from everyone else, until Gris approached and sat down across from Rudo and started chatting. Then Enjin came up behind Rudo and rested his elbow on the white-haired boy's shoulder, claiming he was very tired, or, in his own words, "I'm dead tired." Seeing that the others seemed to have warmed up to the new Spheric boy, you decided to say hello/approach him as well.
