Lightning Sage

Aino raised an eyebrow at the question then answered: "Well, summoning animals are animals that can use chakra. By signing a contract with the animal, you can summon them to aid you."

"What types of summoning animals are there and which are the strongest?"

"There isn't really a 'the strongest animal' between them it all depends on you and how you use them. The third Hokage has the monkey king Enma, that can turn into a staff and Jiraiya-Sama has huge toads that are experts in water and fire Jutsu and Tsunade-sama has the contract to a giant slug that is able to use healing Jutsus."

"Hmm, thanks for the explanation mom."

"no problem." She said and they continued their lunch.

After they were done, Raiden prepared to leave for more training. Since he started with Shisui and Itachi, he has only trained with her if he needs help in chakra control or needs new Jutsu.

'Looks like I don't really need to teach him anything, especially after he enters the academy as he'll be acknowledged by the clan for learning the fireball Jutsu and awakening the Sharingan. He's also training with two of the clan's geniuses, the next clan head and a descendant of Uchiha Kagami.' Thought Aino while realising having genius children might be good in this cruel world, but it also means you won't be able to spend as much time as you would like with them.

'Forget it. I'll just go to Mikoto-nee-san's to play with Sasuke.'

As Raiden approached the training ground he trained in with Shisui and Itachi, he heard fighting sounds and thought Itachi had come back from his mission and was sparring with Shisui, but that wasn't the case. It was someone he had never seen before. He had black hair that was cut in a bowl shape with extremely thick eyebrows and was wearing a green spandex suit with a Konoha flack jacket. He had his Konoha forehead protector around his waist looking like a belt. He had a smile on his face while standing still and extending a hand towards Shisui as if inviting him to do another attack.

"How about we stop here, Guy-san?" Said Shisui while looking towards Raiden.

"Oh! this must be Raiden-Kun, such YOUTH!" Said the now named Guy with a smile.

Raiden looked at Guy then asked Shisui "Shisui-san, is he a friend of yours? He seems pretty intense."

"Haha, let me introduce you. This is Might Guy, a Chuunin who is specialized in taijutsu."

"specialized? How so?"

"You see Guy-san isn't good at ninjutsu or genjutsu, so he focused on his taijutsu and his father before him, was the same. Right now he can defeat a lot of Jonins while only using taijutsu, he's expected to be made Jonin soon."

"Woah! looks like he's really skilled. Is he here to help you perfect your flicker technique?"

"Yeah, but if you need help don't hesitate to ask for help. Guy-san can you explain your taijutsu style to Raiden?"

"Sure, the Strong fist is the name of the taijutsu style I use, its purpose is to cause external damage and break bones. It is the exact opposite of Gentle Fist which is used mainly by the Hyūga Clan. Like your Uchiha style, it requires high speeds, but the most important aspect to practice this style is body strength. If your bones aren't strong enough to break bones without breaking, you can't use it."

"I understand, please continue your practice. I'll observe with my Sharingan and see if I'm able to pick something up."

Shisui and Guy nodded and went back to their original positions about 5 meters away from each other.

Shisui started by flickering away and leaving behind an afterimage, which Guy sent a punch at when his arm went right through. Guy turned around and raised his arm blocking a punch from Shisui then doing a flip towards the back to stabilise himself before he ran back to Shisui's direction.

Shisui flickered again towards Guy, head on this time, Guy threw a punch towards Shisui which he dodged before trying to counter with a punch to his gut, but Guy raised his leg trying to knee Shisui in the shin. Shisui stopped his attack and retreated.

"I guess it's time to get a little serious." Said Shisui before increasing his speed and flickering multiple times around Guy leaving behind afterimages.

"Looks like I'll also have to get serious if I want to survive this speed." Said Guy before releasing a gravity seal he had on himself then dropping two weighted leg warmers. He moved towards Shisui and both of them were moving at a speed that Raiden's one tomoe Sharingan was only able to get glimpses of them.

'Such speeds. looks like Shisui-san succeeded in altering the body flicker to suit him while increasing its speed. Guy-san is a monster, how much weight was on his body for him to be this fast after removing it. looks like if I want to be able to see them clearly I'll need a fully m.a.t.u.r.ed Sharingan.' Thought Raiden after realising both of them were monsters especially Guy. At least Shisui was using a Jutsu modified to fit him perfectly, but Guy was using his body to generate this much speed.

After exchanging strikes for more than fifteen minutes, they sped up one last time with Guy activating some sort of technique that made his body glow with green chakra and Shisui looking like he strained himself for more speed. After Guy activated his technique, Shisui stopped clashing head-on and tried to utilise his speed to get behind him.

Another five minutes later, both of them stopped while panting.

"Pant, pant. looks like you're gonna become a Jonin very soon as well Shisui. You forced me up to the fifth gate. If you encounter someone who isn't speed based it'll be very hard to face you."

"Pant, you too Guy-san. I know that wasn't your all, but I'm happy I was able to push you this much without much experience in this Jutsu."

'He still has the power to spare!!' Thought Raiden entirely shocked that this wasn't his strongest.

"Guy-san, If you are free sometime can I get your help with taijutsu?"

Guy looked at Raiden while giving a huge smile and gave a thumbs up and said: "You're free to ask whatever you want?"

"Shisui-san after I master the body flicker, you have to tell me how you modified it."

"Sure." Said Shisui smiling.

'I've decided. I want to become a speed based ninja.' Thought Raiden while looking at two of the fastest people in the village.
