OC at duel academy

CHAPTER 2

Apparently dad made Cipher (Colton's nickname for less confusion) duel to get in. I was pissed off Cipher could hold his own against dad and could tie me. Anyway I needed to duel against him.
"Let's duel!" We both say.
"I'll go first I play beast of the Pharaoh in defence and 2 cards face down" he said
"I play Gleipnir, the fetters of Fenrir to get a nordic monster to my hand. Next I synchro summon Loki lord of the Aesir, and play 3 cards face down" I said
"I draw and I synchro summon Red eyes zombie dragon and zombie world so my dragon gains 100 atk points for every zombie on the field so it gains 500 atk points"

To make a long story short I lost. I got overconfident and attacked the wrong monster. When the duel ended I realized that everyone was murmuring about the new synchro summoning we did. Some we're looking at us in jealousy, awe, or a look of challenge accepted. Good I'm ready to go against anyone here. After Cipher got over the win we walked back to Jaden and the other two.
"Nice moves." Jaden said
"Thanks but I got to work on being less confident before it gets me in trouble." I replied
"Yeah one day it's going to get you in big trouble, like when you thought that we could take on your dad and Yugi we ended up in the hospital for a few days." Cipher said
"Please don't remind me of that." I replied
"Wait you've dueled against Yugi Muto!" (spelling)
"Yeah not a fun day." I said
"The only reason we lasted as long as we did was because Kaiba and Yugi don't get along." Cipher said. At this little revelation that my dad is Seto Kaiba everyone that heard went slack jawed.
"You're dad is Seto Kaiba!" Jaden, Bation, and Syrus as I learned the others name were exclaimed. This got more people turning their heads and straining to listen to our conversation.
"Not so loud. I don't want everyone in existence to know." I said. Me and Cipher started walking back down the hallway.
"We'll see you guys at the academy." I said.
