The Holy Grail War in Namimori

Disclaimer: This story takes place after the original Katekyo Hitman Reborn manga.

In a small neighborhood in Namimori, lived Tsunayoshi Sawada, the future 10th boss for the Mafia Family, The Vongola. He snored loudly, that not even the alarm beside him could overcome the noise he created, therefore he could not hear the alarm that had been ringing for well over five minutes. The teen's room was a mess, his bedsheets were undone, manga issues were scattered all over the floor and his desk, and a kid wearing a cow suit was sleeping beside him, snoring just as loud as the teen. Six minutes have passed, and the pair did not show any signs of waking up.

But then, someone slammed the door open, "Oi! Tsuna, wake up!" yelled by the voice of Reborn as he kicked the bottom of Tsuna.

The future mafia boss shrieked in pain and jump up, his head crashing towards the ceiling, causing him even more pain. "You're late Tsuna" Reborn spoke, his tiny hands tucked inside the pockets of his tiny pants.

"Reborn! I've told you many times, don't wake me up like that!" Tsuna yelled at the hitman with the body of a baby.

"It's my job to train the Neo Vongola Primo to be punctual by any means necessary" he spoke with a smug smile on his face

"I told you I don't want to become Neo Vongola Primo!" Tsuna yelled back, but his shouting was replied back with a swift punch from Reborn's tiny hand. Small as they were, these hands hit like a truck. Reborn then sat on top of Tsuna's bushy hair.

"Let's go to school, no-good-Tsuna" he mocked as the future Mafia boss stood up and head to the door, ready to start a new day. He quickly ran out of the school, with a piece of sliced bread on his mouth as he buttoned his uniform.

As expected of Tsuna, he arrived late at his school, Namimori high, and was almost attacked by the head of the disciplinary committee, Hibari Kyoya, at the front gate. Inside the classroom, however, Tsuna performed poorly as always, always getting the answers wrong, and sleeping while a teacher delivered a lecture. By the end of it, despite not doing a lot, the brunette looked burned out.

As Tsuna walked out of the school gate, someone behind him yelled, "Judaime!" which caused him to turn around. Tsuna smiled as a white-haired teen with green eyes and black-haired teen with brown eyes approached him. The pair were Tsuna's closest friends, Gokudera Hayato and Yamamoto Takeshi. The pair had been with Tsuna ever since Reborn came into his world, and they have helped Tsuna overcome many obstacles that came into his way.

"Yo, Tsuna! Wanna hang out?" Yamamoto grinned, approaching and patting the brunette's shoulders.

"The baseball idiot here wants us to eat at his father's sushi place" Gokudera grumbled, pointing his thumb at Yamamoto while looking away from him. "But you don't have to come if you don't want, Judaime!" he continued.

Tsuna smiled, "Ah no Gokudera, I'll go! Besides I am hungry!" Tsuna smiled. And with that, the three walked together, towards Yamamoto's sushi restaurant.

It was a tiny restaurant, enough to fill a handful of customers. Today did not seem busy for Yamamoto's father, Tsuyoshi, as there were only the three of them who ate.

The trio sat on the stool, right next to the counter so they can watch Tsuyoshi make the sushi. A few minutes later and the three was finally served their food, "Thanks for the food" all of them yelled at the same time, before digging in.

As they ate, a beautiful woman with purple hair and red eyes walked inside of the sushi restaurant. She donned a black trench coat, black stockings, and knee-high black boots while carrying a black purse. The three locked their eyes at the woman as she sat three stools away from them. As Tsuyoshi approached the woman, a little shy of course, Yamamoto quickly looked at his friends, "She looks foreign don't you think?"

Gokudera nodded, "Yeah but why would a foreigner go to Namimori of all places? This place is as boring as a rock" Gokudera stated.

"You guys quiet down, she's looking at us" Tsuna called, as he stared back at the woman.

The woman glared at the brunette as she noticed the three were talking and looking at her. The sudden hostile stare of the woman frightened Tsuna as he looked down towards his food. Something about her doesn't seem right Tsuna thought to himself as his intuition unexpectedly activate.

"Judaime, watch out for her, she might be a Mafia member" Gokudera warned, leaning to his boss while glaring at the woman across them.

Tsuna gulped and took a quick glance at her again, a slight feeling of unease came to him as he stared into the eyes of the woman. Indeed something about her made Tsuna feel uncomfortable and worried, but he could not tell why nor if he's even right.

After a while, the group finished their food and Gokudera and Tsuna left the restaurant, waving goodbye to their friend.

"Judaime, allow me to accompany you home, I still find that woman at the sushi restaurant unsettling" he said in a serious manner, looking down at the ground, and a face that was dead serious but also worrying.

Tsuna noticed the look of worry Gokudera gave off, "It's fine, Gokudera! I can take care of myself!" he gave Gokudera an assuring smile and a small chuckle.

"If that's what Judaime wants" Gokudera trailed off, with his expression not changing.

The pair split up at a crossroads with Gokudera heading straight while Tsuna taking a turn to the left. They waved each other goodbye, with the two now separated and walking their own paths to their homes.

Soon came night time, and Yamamoto was training at his dojo with a kendo stick. A mysterious figure from outside was watching him, Yamamoto being unaware of this. The figure had the body and hair length of a woman, but her dark outfit masked her identity. The figure looked over the swordsman, glaring at the swordsman, "You can take him out right now, you know?" came another female voice. "If you don't I will" she continued, appearing behind the other women seemingly from out of nowhere. This woman had white hair tied like a ponytail and red eyes. In her right hand, she held an arrow in her left hand and a long bow in her right hand.

"Do as you please, Archer" the dark woman replied.

The woman named Archer aimed her bow at Yamamoto and pulled the string as she attached the arrow. The arrow burst into flames, revealing the woman's outfit. It was a white gi, with the left sleeve revealing a portion of her arm. Behind her was a naginata and clipped to her waist was a sheathed katana.

The woman released the flaming arrow, quickly traveling towards the seemingly unaware swordsman. As the arrow came closer, Yamamoto's eyes glared at the two figures from afar.

"Kojiro!"
