Disclaimer: I don't own anyone but the Spirit Animal crystals, the rat mutant, bull mutant, lizard mutant and the group that attack Leo and Yusuke's transformation.


Lesson 2- Responsibility

In the Ancient One's Dojo, the Ancient One is drinking his tea and thinking about what happen earlier that day when Leo and Yusuke came to his dojo.

"Those two kumquats are both stubborn. Although, Leonardo's self esteem seem to be down causing him to get defeated by Yusuke in the training exercise. Yusuke laughs at him and helps him up. Then Koenma comes with a mission with for them to stop a robber from getting Spirit Animals gems and they left."

The Ancient One was still in his thought when suddenly he hears a door open and shut. The Ancient one knows who it is. He looks to see Leonardo with something in his hand that was small and moving. The Ancient One wonders what it is. Soon a canine's head appears with its tongue out and tail wagging. It is a gray wolf cub. The Ancient One is shocked to see the cub.

"Leonardo, why do have a cub in your hands?" The Ancient One asks Leo who puts the cub down.

"It's a long story." Leo answers as he puts his right hand on his head in shame.

"What troubles you, Leonardo? Where is Yusuke?"

"It's so stupid, that mutant rat we fought…"

"What? Leonardo, what are you talking about I thought you and Yusuke were going to investigate the robberies of the Spirit Animal crystals."

"We were until…"

"Until what?"

"Well, it started after we went to investigate the robberies."

Flashback

Yusuke and Leo are on the roof on top of building in Tokyo. Yusuke and Leo were looking for a demon that was robbing stores at night. Yusuke was starting to get frustrated and Leo was still looking through the binoculars. He soon sees nothing and puts the binoculars down.

"This is so boring?" Yusuke says to Leo.

"I know but the bad guy isn't going to make a noise to lead to them." Leo says to Yusuke.

Suddenly Leo and Yusuke hear an alarm go off near them. They both look to see that a mutant rat is robbing a jewelry store. They soon see the rat mutant with a green jacket and red turtle neck shirt pick up two gems that were both crystal blue in color and he crushes them and two spirits came out: a wolf and a lion and he absorbs the spirits into his body shocking the blue clad turtle and the spirit detective.

"Wow, new powers, I can't wait to try them on some people I know." The rat mutant says in a sinister raspy voice.

"You won't be going anywhere, rat." Leo says boldly to the rat mutant.

"What the hell?" The rat mutant says seeing Leo and Yusuke. "The Ninja Turtle and the Spirit Detective, great, what a day, oh well.

The rat mutant suddenly glows and then runs as fast as a cheetah. Leo and Yusuke go after the rat mutant. The rat mutant glows again and jumps into trees like a monkey/chimpanzee and swings across them trying to avoid the blue clad turtle and the spirit detective.

"Where did he go?" Leo asks.

"His spirit energy keeps changing so I can't sense him that well." Yusuke answers.

"Great, we lost him."

"Not really, Leo." Yusuke points out seeing tree leaves falling from trees up head of them and they both ran after the rat mutant.

"Damn it! Those two are persistent." The rat mutant says as he glows again as starts to hop like a kangaroo. "Got find somewhere to hide… right here."

The rat mutant hops into a warehouse and glows again to camouflage himself like a chameleon. Leo and Yusuke come into the warehouse and look around for the rat mutant. They searched for a few minutes. Soon Yusuke sees a shadow that's not a box.

"I found you!" Yusuke says to the rat mutant.

"Damn it! I guess I have to combine my powers to make me a fighter." The rat mutant says glowing brighter than before. "How about a boxing kangaroo punch, Spirit Detective."

The rat mutant punches Yusuke but Yusuke blocks the punch but he gets kick sweep by the rat mutant like a kick boxing kangaroo. Yusuke growls and he charges up his right index finger. The rat mutant sees it and glows again and jumps like a kangaroo rat very high surprising the Spirit Detective. The rat mutant glows again and sticks to the wall like a spider Yusuke soon follows. The rat mutant soon sees Leo he smiles slyly knowing he can catch the blue clad turtle off guard. The rat glows differently and the wolf spirit comes out of rat mutant.

"Get him." The rat mutant says as the wolf spirit charges toward Leo.

Yusuke sees this and races toward Leo. It happens in slow motion. Leo turns around as the wolf spirit is almost at him but Yusuke gets in front of him and the wolf spirit goes into him causing him to glow. Leo shields his eyes and when the glowing stops, Leo removes his hands and sees his friend's clothes on the floor with a lump where the shirt is. Leo and the rat mutant are both in shock. Leo goes toward the clothes and removes the shirt and sees a gray wolf cub looking up at him happily wagging his tail. Leo is in shock and soon turns to anger.

"You!" Leo says in anger

"Uh oh, wrong person." The rat mutant says glowing and flying like an eagle but before he completely leaves he is surprised by Leo's sword coming at him it hits him shredding some of his fur. It falls to the floor and Leo picks the pieces up and gets the gray wolf cub into his hand along with Yusuke's clothes.

End of Flashback

"And that's what happened." Leo says finishing explaining.

"So the cub is Yusuke!" The Ancient One asks in shock.

"Yes, I can't believe it." Leo says as he uses his swords to slice the trees.

"Leonardo, it's ok."

"No it's not! It's still it's my fault. I wasn't aware of my surroundings and Yusuke is wolf cub because of it." Leo says angrily more at his self than the Ancient One but the Ancient One hits him in the head. "Ow! What was that for?"

"Leonardo, it's not your fault! Yusuke saved you from being in his predicament. He..." Ancient One starts to say but sees chewing through his clothes. "Leonardo! Take Yusuke away from my clothes now!"

Leonardo grabs Yusuke and takes him outside. Yusuke wags his tail happily and sniffs around and he sees mud puddle and jumps in it. Yusuke pants happily and shakes his fur and throws mud into the Ancient One's clothes that hanging on his clothesline.

"Leonardo! Get Yusuke away from my clothes now or I'm putting him out in the woods!" The Ancient One yells angrily.

"Come on, Yusuke, before the Ancient One gives you to wild animal in the forest." Leo says as he picks up the muddy cub and takes him to the lake near by and washes him off with soap and water. The cub howls happily and Leo smiles back and pets Yusuke on the head. "Don't worry, Yusuke, I'll change you back some how even if I have to find the rat mutant that did this to you."

The cub barks as if he understood Leo. It is nightfall and Leo is in bed. He soon hears yip and a whimper. He sees Yusuke on the side of him looking at him with sad eyes. Leo picks up Yusuke and puts him on top his cover and Yusuke soon walks around and lies down and falls asleep. Leo smiles at the sleeping cub and goes back to sleep. It is the next day and Yusuke barks to wake up Leo. Leo gets up and yawns and takes Yusuke outside to let him go to the bathroom.

"Ancient One, I'm going to find the rat mutant." Leo says to the Ancient One.

"Be careful, Leonardo." Ancient One says.

"I will. I'm taking Yusuke with me."

"Good."

Leo soon leaves under a disguise with Yusuke on a leash. The cub barks happily. He soon chases his tail. Leo laughs a little. Yusuke suddenly growls seriously catching Leo's attention.

"What is it?" Leo asks looking at the ground seeing the same fur that is in his hands. "The rat mutant! Ok, boy, lead me to the rat demon!"

Yusuke starts sniffing and then running toward an alleyway. Yusuke scratches at the wall. Leo stops at the alleyway and sees Yusuke scratching at the wall. Leo is confused but feels on the wall and his hand seeps through one part of the wall. Leo realizes this but before he goes through, Yusuke goes through first and barks and runs to the rat mutant who talking to a cohort of his.

"Look, I did something that no one could do…Ow! Damn it!" The rat mutant yells feeling a bite on his tail. He lifts his tail and sees the cub on his tail. "Look, I turned the Spirit Detective into a wolf cub see."

"That can't be Yusuke Urameshi!" A mutant bull says.

"It is! Look at the eyes."

"You're right!" A mutant lizard says looking at the cub's eyes. "Now, that he's a cub he won't be able to stop us."

"But I will." Leo says seriously with his katanas out.

"You, ninja turtle, please."

"I will!" Leo says charging toward the mutants in the place. All of the mutants charge at Leo and they all fight with Leo kicking some of them and slashing others. Then the bull mutant grabs Leo and the other mutant jumps on him and starts beating him up. Leo growls angrily and tries to get out but they kept being him until suddenly a glow occurs as all of the mutants shut their eyes to block it out. When the glow stops the mutants take their hands off their eyes and they soon see a familiar person in front of them.

"Well, guess who's back?" The voice says as he cracks his knuckles.

"Yusuke Urameshi!" The lizard mutant says in fear.

Yusuke charges at the mutants on top of Leo and he beats them up with punches or with his Shotgun blast. After the last mutant falls, Yusuke picks up Leo who passed out from his adrenaline going down. Yusuke comes back with Leo and the Ancient One is in shock but smiles knowing that his lesson went through.

"I see Leonardo gained his self esteem back." The Ancient one says.

Yusuke nods and puts Leo down on his sleeping bag. Yusuke soon sits near the sleeping bag and waits for Leo to wake up. It was at night Leo woke up and looks around and sees Yusuke sleeping by the wall near his sleeping bag. Leo is in shock to see Yusuke.

"Yusuke, is that you?" Leo asks still in shock.

"Yeah, Leo. It's me." Yusuke says sleepily.

"So did I…"

"You pass the Ancient One's test, Leo, you got your self esteem back."

"Well, yeah, it was thanks to you."

"You're welcome now go to sleep before the Ancient One wakes up and start our training early."

"Ok, good night."

"Good night."

So the two leaders went to sleep but the Ancient One still woke them up early causing Yusuke to glare at Leo and Leo sheepishly smile and they start their training with Ancient One watching.

The End…
