Another World But I'm The Strongest

Chapter One:

A guy with long dark blue hair and golden eyes was fighting in a judo match. He was wearing a Judo uniform with a black belt. He easily defeated the opponent by flipping him to his back.
"Winner, Hiroshima."
"Amazing, Hiroshima-san is so strong," a guy said.
He helped the other to his feet. This man was named Hiroshima Seiya. He was a second year in college and a master of all mixed martial arts. He even learned kendo and mastered the sword as well. Seiya yawned as he he looked emotionless.
"It's all so boring," Seiya thought.
"Seiya-chan," a third year shouted before hugging him from behind.
He instantly flipped him into the tatami mat.
"Yeah I probably shouldn't have done that, sorry," he said.
"Kagemine-senpai," Seiya said with a blank stare.
Kagemine Ryou, a third year and childhood friend on Seiya.
"Seiya-chan is too beautiful, and he's strong too," Ryou thought.
Seiya helped him up and sighed.
"Don't hug me from behind," Seiya said.
"Sorry, Seiya-chan," Ryou said.
Ryu patted him on the head and Seiya glared.
"Seiya-chan?"
"Why are you patting my head?"
"Because you're so short."
"I'm not short, all you motherfuckers all 200 cm (6ft), I'm 180 cm (5ft 11), it's not that far. I'm average height damn it," Seiya shouted.
"Aw, you're so self conscious," he said.
"Whatever, I'm heading home for the day," Seiya said.
"Okay, see you later," he said.

He changed into a gray sweatshirt and black sweatpants. He left the school and began walking back home. A child lost control of his ball and began to run into the middle of the road. There was a truck about to hit him.
"Watch out," Seiya shouted.
Seiya immediately ran and pushed the kid out of the way.
"Shit, this is how I die," Seiya thought.
A magic circle appeared around Seiya and glowed a bright white. Seiya was hit by the truck at the same time, and he fell unconscious. Soon the circle made him disappear and teleport elsewhere. He appears in a magic tower. There were clerics, magicians, and royalty waiting to greet him.
"Woah, it worked," one of the magicians shouted.
"What do you mean it worked," a guy asked.
"It was pretty experimental, and we didn't think we could summon another worlder," the leader magic researcher said.
"Che, you're just lucky it did. If it didn't, you would be held in contempt for lying to the Royal family," someone said.
Someone walked over to Seiya and crouched down.
"Prince Kyouya, your highness," people said as they kneeled.
The man was named Katsuwari Kyouya. He was the second prince of the Reinheld Empire. He is also the strongest in the kingdom and the royal guard captain. He has blonde hair and bright green eyes. He wore a blue blazer over a white buttoned-down shirt and a red tie. He wore black dress pants and black shoes. He smiled as he saw Seiya's sleeping face.
