Then just after the incident where just after Tsuna had accepted Hayane as his guardian when once again the local Yakuza who had wanted to defeat Tsuna to increase their reputation but which were beaten up by Hayane as returned to her original attitude she once again was about to throw Dynamites as the Yakuza.
Today at the usual training ground that tsuna and his friends located in the forest behind Namimori high, Tsuna introduced Hayane to his friends as a new follower. Hayane had gotten along with most of them except with Kyou, Ryohei, and Takeya.
Hayane didn't like Kyou because Hayane thought she was too arrogant and didn't even seem to think of Tsuna as her boss, but Tsuna just told Hayane that Tsuna doesn't like it when people mostly treat him as a superior and rather treat them as equals.
As Hayane heard Tsuna's reasoning, she felt even more proud to serve a boss like Tsuna. But although she agreed to what Tsuna said, she still challenged Kyou to a fight. But most of the gang thought that Hayane would lose as they all knew that the strongest member of their group aside from Tsuna was Kyou.
Predictably Hayane did lose; however, she was able to fight back for a bit before losing. It seems the Hayane, unlike Hayato from ??? memories, due to Hayane being a girl, could get more attention from Shaman and get him to teach Hayane more effectively. Due to this, Hayane was now more proficient than Hayato from ??? memories in using dynamites. Although rarely, Hayane does know how to control mosquitoes as Shaman does as Hayane prefers using her dynamites.
Then, although they can get long, Hayane found Takeya as her rival as Tsuna's right-hand woman as although everyone was strong in the group, Tsuna introduced the one who seems to act almost like the right-hand woman of Tsuna was Takeya.
Takeya saw how Hayane was treating her, but she just shrugged her off as she thought most of what Hayane was telling was a joke as she's Hayane to be her friend already. Although Hayane didn't like Takeya, although she does not say it, Hayane considers Takeya to ber her trusted ally also a rival.
Then finally to Ryohei, similar to Takeya, Hayane considers Ryohei to be his rival. However, both of them often call each other names immediately after meeting each other, with Takeya separating both of them if they go too far. When Tsuna saw this, he just sighed as it seems that from ??? memories, although some of Tsuna's world was different from ??? memories, most of his friends still had similar personalities like their counterparts.
Then after introducing Hayane to everyone Tsuna bought a set of 5 rings similar to Future Gokudera's System C.A.I. When Hayane saw Tsuna bringing out 5 rings from out of nowhere, and the rings were even looked liked the rings which were very rare in the mafia world, she was stunned. But due to Hayane's natural belief in Tsuna, she shrugged it off again and thought it would be natural for a boss like Tsuna many of these rings.
Then at first Hayane didn't know why Tsuna gave her 5 rings as she thought that she only needed one. Then Tsuna and Reborn said that both of them had used a special means to see someone's death will affinity and when they took a look at Hayane she had 5 dying will affinities which was very rare.
The most compatible flame of Hayane which was Storm and the other four flames were Lightning, Rain, Cloud, and Sun flames. When The gang besides Tsuna. Reborn and Kyou heard this they were surprised as they only knew Tsuna had 4 flames currently but Hayane herself has 1 more dying will affinities that Tsuna.
When Hayane heard this, she was surprised and then she wore all the five rings on her hand and tried to ignite her dying will flame. Tsuna saw how Hayane was getting a hard time activating her dying will flame so just like from ??? memories Tsuna did the same thing that caused Hayane's flames to awaken.
Due to the help of Tsuna to help Hayane unlock her flames, Hayane was able to unlock her Storm flames, but she was still hadn't able to unlock the 4 others successfully. Hayane was disappointed in herself when she couldn't unlock the others. Still, Tsuna then said to Hayane "Don't worry Gokudera-chan even though some of us was able to unlock our second's flames quickly but you have 5 flames may be in your case it's much difficult to unlock it because of the many affinities you have, and Hayane even if your only able to unlock one now you can still train your Storm flame."
When Hayane heard Tsuna's encouraging words and praise towards her, she didn't become disappointed in herself anymore, and it lit her determination to train more and become strong enough to be able to be equal to Kyou in combat strength to become worth it to become Tsuna / Vongola Tenth's, right-hand man.
Then four days after Hayane had transferred at Namimori which was currently the weekend. Hayane had trained along with Both Takeya and Ryohei in private. The three of them began close friends very fast as their personalities complement each other and also because Hayane was determined to train so she could learn to use all of her remaining Dying will flames.
When Ryohei saw how Hayane's will to train, he became inspired and shouted his usual motto, which was "Extreme". And due to this training, although both Ryohei and Hayane still often fight each other due to some conflicts and still call each others names. Hayane and Ryohei, however, became more closer due to it and considered each other as an ally and a friend. While Hayane also became not that jealous of Takeya anymore.
Today Tsuna was being taught by Reborn about some questions on his studies. Reborn had set up some bombs in case Tsuna had answered a question wrong. Tsuna sighed at this as he thought that if he just got an answer wrong, Reborn would really explode the bomb. Tsuna knew that Reborn wasn't joking as Reborn was not a joker. Reborn questions even more grieved tsuna as the questions Reborn was already asking him was already college level. Still, luckily Tsuna had advanced study already, and Tsuna himself and also Spanner could already graduate, but they chose to go to school, and Tsuna still wanted to enjoy his high school life.
Then suddenly just after Tsuna finished answer one of Reborn's question Tsuna sensed a presence at his window and Tsuna immediately turned around to see a ten-year-old boy who had curly hair with one of his eyes were closed and had # marks on his cheeks and was wearing a black winter jacket which was open with cowhide patterned shirt inside and wearing a horn-shaped necklace.
The ten-year-old boy was standing at the tree near Tsuna's window and was holding a pistol as the kid shouted "Die Reborn!" as the boy shot the bullet out of the pistol.
