Then when the kid shouted it he shot the bullet from the gun he was holding, but as he was aiming the branch the kid was standing on broke and due to this the gun aimed instead at the sky as the kid shot the bullet.
When Tsuna saw the kid fall, he sweatdropped and took a look at Reborn and asked: "Hey Reborn, who was that?" When Tsuna saw the kid, he thought the kid looked so much alike Lambo from ??? Memories but wasn't sure as from the memories it showed that Lambo looked like a baby and not a kid that was already ten-year-old.
But Reborn instead of answering was still focusing on the questions he was Tsuna which made Tsuna thought that maybe the ten-year-old kid was really Lambo as from ??? Memories. But why was Lambo really looking like a ten-year-old rather than a 5-year-old?
Then as this was happening in Tsuna's room, the kid who just fell was about to cry. Still, he stopped the tears before he once again jumped towards the tree again and this time immediately after getting on the branch he jumped through Tsuna's open window and dashed towards Reborn.
Then without even acknowledging the kid's presence Reborn just smacked the kid to the wall with a single punch. Then as the kid stood up from the wall with a bleeding head said: "Hey don't you ignore me. It is I the great Lambo 10 years old, a hitman from the Bovino Familia."
As Tsuna heard this, he finally knew that it was indeed Lambo but felt bad to Lambo also at Reborn seemed that he really didn't care about Lambo's existence in the room. Then as Reborn was still ignoring him, Lambo was now getting angry, and when he tried to show off some weapons and including the ten-year bazooka which Tsuna was most interested in now.
Even from the system items that can change or manipulate time had cost very high and even the cheapest ones cost him 2000 points and above which a bit disappointed Tsuna as his system rarely gives out quests and most of his quests if he was given only Tsuna some exp and nothing else.
Then as Tsuna thought this Lambo couldn't take it anymore and finally threw out to Reborn a ton of grenades, but Reborn still ignored the kid and caught the grenade and threw it back to Lamb which caused Lambo to get thrown outside with the grenade.
Tsuna himself being worried said to Reborn "Hey, couldn't you've been a little nice to the kid." Then Reborn replied "I can't most people think that the Bovino family was a small mafia group in Italy, but in reality, the Bovino is one of Vongola's secretive and strongest allies. The Bovino family, unlike most groups, doesn't do much in the mafia world and almost all the members of the Bovino family are researchers who are interested in space and time technologies. And also as a request from the first Bovino boss years ago the Vongola familia to take on at least one member of it to join each generational boss of Vongola's boss guardians. As the Bovino familia is a group that was started by descendants of the first lightning guardian of the Vongola. "
Then as Tsuna thought this was great new info Reborn then said: "And the reason I kicked that cow kid out is that I don't like annoying kids." Tsuna sweatdropped when he heard this then as he was thinking of this Nana called him from downstairs and said: "Tsu-kun there seems to be a kid here can I think he's a friend of Reborn-Kun's friend."
When he went down and saw Lambo with a dusted (clothes) due to the explosion with a tear coming to his eyes a bit, Tsuna sighed and went outside with the crying Lambo for a bit. After an hour of talking with Lambo and trying to calm him or stopped him from crying, Tsuna found out that Lambo's last name was Bonvino and also that Lambo was one of the possible candidates to be the next Bovino familia but due to his attitude and as he was the youngest candidate, so he wasn't really considered as a candidate against Lambo's relatives who were also potential next Bovino boss.
Then after knowing more about Lambo, Tsuna and Lambo headed back to Tsuna's house while Lambo was eating a candy that Tsuna gave him earlier. On the way home, Tsuna had met up along the way with Chrome who was earlier was at the mall along with Kyoko and Haru. Then when Chrome saw Tsuna along the way she said: "Oh boss where did you come from I thought Reborn-san was teaching you today about your lessons at this time, And Boss who's the kid next to you."
Tsuna then explained the situation to Chrome, and after listening to Tsuna's explanation and how he ended up here along with Lambo while, Lambo himself was currently playing Tsuna's phone which Tsuna earlier put in his inventory and gave it to Lambo temporarily. Lambo was surprised how Tsuna brought out the phone from nowhere and due to his childishness and not knowing how important the info was Lambo then thought that Tsuna had a device that the Bovino familia made.
Then due to this, Lambo told many things about the Bovino research which although Lambo only knew little about still provided a good amount of info for Tsuna. Tsuna warned Lambo that he shouldn't tell it to just anyone and just nodded. Lambo didn't know about it, but it seems that Tsuna's personality caused him to trust Tsuna immediately. Although they had just met recently, he already had thought that Tsuna was like an older brother to him.
When Chrome finally heard all of Tsuna's explanation they were both walking back to their house and then Reborn suddenly appeared from nowhere and using a transformed Slipper Leon smacked Tsuna's head and said: "Hey No-Good Tsuna why did you take so long did you think you can escape from our training it's been an hour I did not say you could rest yet earlier hmm." As Reborn was releasing an intimidating aura towards Tsuna alone.
When Lambo saw Reborn again, he remembered what was here for again he took out another grenade and threw it once again to Reborn but, This time Reborn threw the grenade back at Lambo which caused Lambo to get hit into the wall in the street again. Chrome was surprised due to Reborn's immediate reaction towards Reborn and actually felt bad for Lambo.
Then due to this hit, Lambo finally snapped and started crying, and then from his hair, Lambo had taken out his ten-year Bazooka. Then as Chrome saw the bazooka when she saw that Lambo was aiming at himself, she was about to stop Lambo as she thought it might kill him but couldn't stop it.
Then after Lambo shot the bazooka to himself a puff of smoke came out and then the trio saw a 20-year-old Lambo who had longer hair that covers his left eye who wore a dark green coat with beige fur with a cowhide shirt. And also wore black fingerless gloves, his brown belt had a grey buckle in a horn shape with two other belts around his belt, his pants were black, and he wore brown shoes.
Then Tsuna was surprised as the older Lambo looked really mature and seemingly not a cry baby anymore as when the older Lambo seemed to have no problem with Reborn unlike from ??? Memories which showed that the 15-year-old who still had problems with Reborn.
Then when the adult Lambo saw Tsuna, he seemed to be happy and said with a graceful attitude and voice. "Hey, young Big bro and Chrome-dono nice to see you both of you today, and before you ask anything young boss your older self told me not to say anything yet and said that you'd find about it soon."
When Tsuna heard this he was stunned along with Chrome who had just seen a 10-year-old turn into a 20-year-old although she knew many about the supernatural world and mafia world by now due to Reborn's lecture this week, she didn't think that time travel to be real. She knew it was really time travel as she hadn't sense any supernatural energy or mist illusions that happened in the area inside a 50-meter radius.
