The Colosseum was one big dome, which was then surrounded by smaller ones surrounding it. It was used to train the army, which's sole purpose was to defend the city from demons. The army had five ranks: White, Red, Blue, Purple and Black. The ranks were used to differentiate between the soldier's strength in the army. On your first day, you are given the White belt, which later through victories and achievements can be upgraded to a better and higher rank. Both Ren and Izumi started their career as a soldier yesterday, which meant that they had both White belts. The domes surrounding the Colosseum were to segregate ranks, all of five of them received different types of training. The massive one in the middle was used for official meetings, mixed training, enemy briefing, mission assignments and also the residence of the captain. The single greatest entity of the Cloud City, Jin Serugu, he is known to vanquish an entire army of demons with a single flick of his golden katana, his bright, silky white hair makes even the most handsome of men envy him. His very rare ability to control every single element is also very impressive. He just yesterday turned 35, which meant that he was officially the first captain to ever survive into their middle age. All the other captains were either killed by demons or died with illness.
Izumi and Ren enter the building, which from the inside looks exactly like how Izumi saw 2 years ago, when he was here for a city tour for merchants, done by his friend, Evan. There was a massive sea of soldiers waiting excitedly for their squad assignments with their guardians, parents, that word was thought about so less in Izumi's brain, that he almost forgot it. He and Ren were both orphans of prestigious clans, but their parents died when they were both 6 due to corrupt officials in the city, who later were served justice by the then newly elected captain, Jin Serugu. Izumi didn't mind families getting affectionate in front of him, but when he saw a mother straightening the belt of his son, smiling warmly, he couldn't help but wonder, would they have done the same? Would his father give him a few pats on the back and then words of encouragement? Would his mother prepare him in his clothes, so he looked presentable for the big day? Moreover, Izumi was more worried about Ren, as he glanced at his side and saw his neck muscles tighten, and his eyes slowly losing their shine. Izumi didn't try to stop Ren from getting nervous, he would hate it if Izumi comforted him, and he looked weak. Then they both feel a hand on their backs. A very powerful presence.
"Hey kids" Jin Serugu smiles enthusiastically as he pats both of them on the back.
