~Monday Afternoon~

Everyone's out in the school field, Yami made it into a flat ground by using his mach speed to remove all the weeds, soil and trees turning it into a field where everyone can use in their Pe time.

This time Kurama is teaching the students in attacking, everyone got their knives and they were told to attack Kurama one by one or in groups.

"Kurama-sensei, you'll lose if we did grouping you know!" Marik stuck out a tongue at their teacher.

Kurama smirked his eyes closed and arms crossed. "Let's see you all try."

"Heh, Kurama sensei's acting all cool." Joey grinned at Yugi.

"Yeah, I'd like to kick his ass and shove it on his face when I do." Yugi was smacked in the head by his friend Anzu.

"Yugi! He's a retired assassin, you know." Anzu exclaimed at him.

"We know that. That's why it'll be awesome when we do kick his butt." Honda went to where they are and watched Marik and Otogi attack Kurama in pair.

'They're good when fighting together but that doesn't mean I'm gonna lose.' Kurama quickly went behind Marik and saw Otogi attacking. He dodge the attack and was received by Marik. They both fell on the ground scratching their backs.

After that students began attacking Kurama and now Joey joined them and Yugi too.

Joey was fighting Kurama and was running around in circles. When Joey went for an attack behind, Kurama quickly turned facing Joey. Joey quickly backed off grinning.

'Looks like he knows when he can't win a fight huh?!' Kurama thought and suddenly he felt a cold snake like atmosphere behind him. Because of his instincts and reflexes, he quickly turned and saw someone almost near in getting a knife on his neck and got the students arm and hitting him hard.

When Kurama saw who it was, his eyes widened in shock. "Yugi! I'm sorry." Kurama went to where Yugi who's groaned from the pain.

"It's okay Kurama-sensei." Yugi got up by the help of his friends.

"Class is dismissed now" Kurama told everyone and they went home.

~Teacher's room~

'I felt cold back there. I almost didn't notice Mutou's presence.' Kurama was on his seat thinking deeply.

"Thinking about what happened back there with Yugi?" Kurama was snapped out of his thoughts and looked up to see Yami smirking at him.

"Yeah, I don't know why though." Kurama sighed.

Yami made his way to the window. "He's really something, I tell you. Even though you'll see him as an adorable and cute and fluffy and-"

"I get it just finish what you're really going to say." Kurama exclaimed stopping Yami's words for Yugi.

"Ahaha, okay. Even though he looks harmless and a person who looks like he get's bullied. You'll be really surprised knowing he can be putting a knife at your throat in a quiet way like how snakes do."

"I know, I should probably get a replacement teacher for their physical education period."

"Is that what you really want?" Yami turned to Kurama with a serious look on his face.

"Yeah." Kurama looked at Yami's eyes proving he already decided.

~Next Day~

"Hey guys, where's Kurama sensei?" Honda asked the gang.

"We don't know he's taking too long." Joey breathed out heavily.

"Oi, look someone's coming here." Ryou pointed at a blond tall man walking towards where they were.

Everyone looked as the man neared their place. The blond man smiled and had a  big bag with him. "Hello everyone I'm Keith Howard. Nice to meet you all. I'll be a substitute to your teacher Kurama."

After he said that Kurama went to the field and looked at everyone. "Don't worry class, Keith and I go way back in the military. He's a good guy and he can really help you out with your assassination skills." Kurama looked at Keith nodding.

Next thing Keith took out a lot of sweets and invited the students to come over and have a treat for a while. The other's saw Yami drool. "Oh, Yami-sensei. You can have some here." Keith invited waving his hands.

"Is that okay?" Yami asked with tears of joy flowing down his face.

"Of course." Keith said cheerfully and everyone had fun in their class and thought it would be better if he was their teacher.

~Next Day~

In PE class everyone was outside and were doing a lot of push ups. Keith told them to do so.

"Now, put more spirit into it. Remember it's a hundred push up, laps around the field and a hundred kick in this pad." Keith grabbed a red big pad used for martial arts and laughed sadistically.

'Tsk, how did it turn out like this.' Joey gritted his teeth through the push ups he was doing.

Yugi was looking at everyone with down faces and exhausted ones.

~Four days passed~

Yami couldn't bear to see his Yugi suffering these past days, Kurama can't do anything after knowing that Keith's past students were beaten up to work hard and follow him.

"Tch, Kurama can't we do anything about that guy." Yami growled underneath his breath looking at Yugi and the others exhausted and tired and were still doing push ups.

"If only I knew he was like that. I wouldn't have called him." Kurama punched the wall beside him

-------In the field---------

Yugi was covered in sweat along with everyone. Next thing that happened is he saw Anzu flopped down in tiredness, she was breathing heavily. He saw Keith walk where she was.

"What are you doing little girl?" Keith asked angrily.

"I-I'm sorry, I'm just so tired. We've been doing this every day and You're taking all the time of the other subjects." Anzu cried out and suddenly she was kicked on her stomach repeatedly.

The others quickly stopped what they were doing and stood up looking at Keith.

"Oi, you stupid ass teacher. Stop the fuck you're doing." Yugi yelled out making Keith look at him and stop kicking Anzu.

"What did you say boy?" Keith was moving towards Yugi and in a flash Yami was between the two. He was looking at Keith.

"Stop, Keith. You can't do this or what you did before. I'll break you if you touch him and the other students." Yami warned Keith and saw him smirk.

"Heh, like you can. If you did that you're reputation as a teacher would be tainted and you think the director's going to be on your side?"

"Shut up, Sensei. You're not a damn teacher so get out of here." Valon shouted making everyone do the same.

Kurama quickly went there and saw what was happening. He neared Keith and placed a hand on his shoulder. "Keith stop this." Keith turned and looked at Kurama.

"And if I don't want to? You asked me here so I better finish training these losers till they can have a chance killing that monster." Keith laughed pointing at Yami.

He stopped and faced Kurama still looking serious. "Alright since your my former bud back in the days. Let's have a deal if one of your students beat me. I'll leave and never return. How about that? If they don't I'll make them suffer everyday and you can't say anything about it or you can't also stop me." Keith grinned deathly at Kurama.

"Deal." Everyone went quiet and Keith got a knife and handed it over to Kurama.

"If your students manages to land on me, you win."

Kurama looked at the knife and at his students he was having one of those biggest choices where you need to pick the right one for this. All of a sudden he found himself in front of Yugi. Everyone went shock.

"Sir, why Yugi?" Honda looked at Kurama disbelievingly.

Kurama ignored and looked at Yugi, "Yugi, I know you can do this most of the others/ I... I trust you" Kurama said and saw Yugi take the knife.

Yugi smiled at him, "Don't worry sensei, I'll finish this quickly."

Yugi walked towards Keith and distanced their selves a few meters away.

Keith laughed. "Kurama, you're students are dead. Well, let's begin shall we?" Keith looked at Yugi mockingly.

Yugi made a stance, 'I can't win this battle, but it's not about winning, I just need to touch him with this and it's finished.' Yugi looked at Keith. He looked down and breathed.

"Lost your nerves Kid?" Keith teased and saw Yugi look up smiling. Yugi then walked forward smiling at him.

'What the heck is he smiling for?' Keith watched Yugi still smiling and soon he felt Yugi bump him.

What shocked Keith is that in an instant, he was on his knees whimpering and was scared feeling Yugi at his back and the knife on his throat touching.

"Gotcha." Yugi said happily smiling at Keith.

Everyone were in shock also, 'Yugi just..' Joey couldn't believe, everything was so fast.

Yugi stood up and walked in front of Keith, "As a deal you leave this school sensei." Yami said walking beside Yugi and ruffled his hair. Keith quickly scampered away from the humiliation and because he was afraid.

"Ohh, that's my Yugi-chan!!" Yami hugged Yugi tightly planting kisses all over Yugi's face.

Everyone laughed and surrounded Yugi.

"That was awesome dude." Joey nudged Yugi's side and saw Yami growl at him. 'Shit, he's at it again. Damn possessive damn extraordinary teacher.' Joey backed away.

"Sensei, get the heck off me" Yugi squirmed around Yami's hug.

"No!! I never thought you'd use that adorable smile of yours." Yami nuzzled his cheek on Yugi's cheek.

"Sensei, stop that. You're making him melt." Ryou chuckled and everyone laughed. They fell silent when they saw Yami kissed Yugi in front of them. Yugi blushed a ten shades of red.

After the kiss Yami was smiling at Yugi happily. Yugi breathed in and out, "YAMI SENSEI!!!" Everyone yelled and saw Yami run back to the school.
