In the inn Tenko goes to his father with a nervous look on his face as his father was reading the newspaper. "Daddy, I'm very sorry for sneaking out but Umm since we will be leaving tomorrow would it be okay if I can go out to play? I want to see my friend before we have to leave." Tenko asked his father whom was silent for a few seconds. "Fine, you can go out today since there hasn't been any news of the murders but just be careful." He tells him making Tenko happy as his father gave him some money and Tenko goes out to see his friend.

He goes up the mountain and sees Naruto was waiting for him wearing the same hoodie he gave him with the hood up hiding his horns. Naruto then looks at him as he noticed him and smiles at him. "Hi sorry to keep you waiting." Tenko says to him smiling at him making Naruto blush. "I wasn't waiting." Naruto says as he turns away from him to hide his blush.

"I'm glad you're here...I Umm didn't want to leave without saying goodbye." He says to him making Naruto's eyes widen at that as he clenches his fists and grab onto his shorts tightly he felt his heart aching at the news. "Right...I see." Naruto says as Tenko smiles at him. "So Umm I thought it would be fun for us to spend and play with each other all day." He tells him making Naruto turn to him as he tilts his head a bit.

Moments later they were on a bus heading towards the zoo that was in the fire country. "You really never been to a zoo before?" Tenko asked him in shock making Naruto look down at his feet as he had an annoyed look on his face. "Is it fun looking at all the dumb animals?" Naruto asked him sounding annoyed making Tenko. "Yeah it really is, I especially love animals you can't see anywhere else." He tells him happily.

"You're totally not a human!" Sasuke's voice pops into his head making Naruto scowl to himself. "I'm not interested in seeing dumb animals." Naruto mutters out as the rest of the bus ride was tense. When they arrived at the zoo Naruto was standing before an elephant looking excited as he giggles and swings around all happily. "Wow, this is amazing he's so big he's huge how does he get this big!" Naruto says excitedly as the elephant trumpets out making Naruto cheer at this excitedly with his arms pump up in the air.

He then felt Tenko watching him as he turns to him and blushes with embarrassment as they walked off and Naruto tries to act like he wasn't having fun but was failing miserably. "It's not like I'm having fun or anything he just surprised me is all and...wow look at that neck!" Naruto yells out pointing to the giraffe and running towards it. "Wow it's amazing it's completely amazing!" Naruto says excitedly making Tenko smile a bit. He was glad his friend was having fun.

"Here." Tenko says handing Naruto a cup of Italian ice. "My daddy gave me some money so we can have a snack while here." He tells him and sits down next to Naruto on the bench and Naruto looks at it with curiosity and takes some on the spoon and eats it. "Wow it's sweet." He says making Tenko beam at this and making Naruto blush. "But it's kinda cold." He tells him making Tenko giggle. "Well of course it is, it's made out of ice." He tells him as they eat their snack for a bit and once they were done they threw it out and Tenko grabs his hand.

"Hey let's go look around some more." Tenko tells him making Naruto smile and blush. "Sure." He says and they both begin to walk together hand and hand but while walking Naruto remembered how Tenko told him that they are going to be leaving tomorrow which made him scared since he doesn't want to lose the only friend he has and be all alone again.

Naruto closes his eyes and holds his hand with two hands not wanting to let go. Tenko stopped and looks at him. "Hey what's wrong?" He asked him as Naruto was silent and then he gulps. "So Umm tomorrow when are you leaving?" He asked him curiously and Tenko was silent for a few seconds. "Well my family are going to this festival before we leave so Umm we will be leaving afterwards at night time and we will be taking the plane back." He tells him making Naruto nod his head in understanding.

"I see...well umm would it be okay if I can go to the festival with you too?" Naruto asked him in a shy tone blushing as Tenko frowns. "Sorry I promise my sister we can go together already." Tenko says to him apologizing to him making Naruto gained a sad look on his face. "Oh okay...well I guess umm I can see off at the airport then." Naruto says to him making Tenko smile and nod his head yes.

He actually liked the idea of the pink haired horned omega would come by and say goodbye to him before he had to leave. "The good news is that we will be coming next summer though so we can play with each other again when we return." He tells him making Naruto smile and nod his head in understanding.

They then continued to walk around for awhile as Tenko was now looking at the large map trying to figure out where they should go next as Naruto was standing by waiting patiently while he did he overheard some people talking about the murders he committed. "Hey did you hear, I heard that some more bodies were found." The man tells the woman whom was sitting with him. "This is the third one right? It's getting kinda scary." She says making the man scoff. "What are the shinobi doing? It's a joke." He says making Naruto curse and bite his thumb nail a bit.

"Looks I need to kill again if I want a place to sleep." Naruto says to himself but then his eyes widen in horror when he realizes what he had said. "Kill again?" He says sounding horrified. "Did I really just say that? What's wrong with me? Why do I think about killing all the time?" He asked himself out loud that's when he heard it...the voice.

"It's because you like killing people isn't it?" The Voice says to him and Naruto feels chills go up his spine and he feel sweat dripping down his face a bit. "No I don't." He says as the voice continues. "If you don't kill the humans then the humans will kill you it's only a matter of time." The Voice tells him but Naruto shakes his head trying to make the voice go away.

"That's no excuse I can't keep killing people who haven't done anything wrong." Naruto says to the Voice. "You should of figured it out by now...that it is my destiny to take human life." The Voice tells him making Naruto covers his ears with his ears trying to desperately block it out.

"Shut up!" He yells out not knowing that Tenko was now next to him. "Hey what's wrong?" The black haired young alpha asked him with concern making Naruto jolt a bit. "Oh it's umm nothing I'm just feeling a little hot that's all." Naruto lies to him making Tenko smile. "Hey I know a place where we can cool off." He tells him making Naruto look at him with curiosity.

"Huh?" He says and Tenko grabs his hand drags him off. Moments later Naruto and Tenko were at stream of some kind as they both had their shoes off and Naruto had his feet in the water smiling. "Wow the water feels amazing." Naruto says enjoying how it felt on his feet. "Hey." Tenko says getting his attention making Naruto turn to him and then had water splashed on his face. "Your face is dirty!" He says to him and then begins to laugh making Naruto's eye twitches and he gains a strained smile.

Suddenly though Tenko was pushed into the water as he lands on his butt getting soaking wet as well with Naruto standing in front of him smirking at him. "Now it looks like you're the one who needs a bath." Naruto says to him in a taunting manner making Tenko pout angrily and stand up and grab his leg knocking him into the water as well. They then spent the next several minutes splashing each other with the water soaking themselves down to the bone.

After they were done playing in the water they sat by some rocks where their clothes were drying in the hot sun as Naruto's horns were
showing again. "We won't be able to go on the bus until our clothes are dried." He tells him making Naruto frown a bit. "So today, it's really our last time together until next summer huh?" Naruto asked him feeling sad at the thought since Tenko was not only his first friend but also his very first crush.

"Yeah." Tenko says and then he begins to hum the song from the music box making Naruto hold back his tears and he hugs him from behind startling Tenko. "Tenko, this has been the best day of my life nothing else comes close I won't ever forget this day...not for the rest of my life." Naruto tells him crying as this was the single best day of his life where it has been nothing but a living breathing Hell but now...now it felt like it was all gonna be taken from him as he wished that Tenko didn't have to leave.

They were now on the bus as Naruto's eyes were puffy a bit from crying. "I don't want him to leave...if he leaves I'll be all alone again what should I do?" Naruto thinks to himself but then he felt dread overcome him when heard the voice once more. "Then kill him...if you kill him then you won't be sad from him leaving and he won't have a chance to break your heart." The voice tells him making him clutch onto his ears.

"No I won't do it just shut up who the Hell are you?!" Naruto yells at the voice. "As if you didn't know." It says with an evil tone as Naruto returns to reality he sees that to his horror he was strangling Tenko. He then stops and pulls away from him. "I'm so sorry are you alright?" He asked him and Tenko coughs and breathes again. "Yeah I'm okay are you alright? You acted so strange there you scared me." He asked him with concern as Naruto cries and pulls his knees close to his chest and hugs them close.

"Tenko...can I ask you to do me a favor? If I kill a lot of people...if I can't find a way to stop myself...then Tenko I want you to kill me." Naruto asked him while he looks up at him tears were coming down his face shocking Tenko at the request as he rubs the Diclonius's head. "I won't let that happen since one day I'm going to be a hero and I will protect you from that okay and no matter what happens I'll always come and save you." He says to him with a smile on his face making tears comes down his face.

"You promise?" Naruto asked him making Tenko smile at him brightly. "I promise." He says to him and they locked pinkies with each other. The bus then stops and they get off together as they got off Tenko waves goodbye to his friend and heads back to where his family is and Naruto smiles and waved goodbye to him a blush still on his face as he heads off to find a place to sleep for the night while thinking about telling Tenko how he feels about him at the festival without knowing at all that was the last time he would ever see Tenko
