As soon as the doors are opened Hiroto is hit with a chakra presence, he felt familiar with that chakra even though he never sensed it.
"Come in" Brutus motioned him to follow with the tail.
Hiroto stepped inside, his eyes wandered around and found stacks of books which are stacked on shelves perfectly, he also found no trace of dust in the building or the books implying everything in there is well taken care of.
Hiroto saw the crocodile leader come to a stop so he came to Brutus's side with Kaimana on the other side. Hiroto came face to face with a sword lodged in the floor, the katana has a red wave-like pattern on its sharp edge side.
Hiroto noticed the Yin-Yang symbol on one side of the Blade collar, he moved to see the Uzumaki clan symbol on the other side of the blade collar. Hiroto observed the guard of the blade to see six inverted Magatamas forming the guard.
{imagine 6 with the rounded part coming outwards the blade}
Hiroto then moved to see the handle of the katana, cord wrap of black color, and ray skin (gaps between cord wrap) ocean blue color matching his eye color. Hiroto saw the pommel of the blade reflecting the shine of metal so that it could be used as a blunt end. Hiroto instantly fell in love with that katana but held himself back from holding it in his hands. Hiroto looked around and found its scabbard with a mixture of black and blue colors.
"Do you like that sword?" Brutus asked seeing Hiroto eyeing the sword with fervour(fervor).
"I would love to hold it" Hiroto answered.
"Even if you want to, it has to deem you eligible to be its user" Brutus said.
Seeing a confused expression on Hiroto's face Brutus continued "That katana is no ordinary one, it has been passed down in the royal lineage of the Uzumaki clan since times immemorial. The last user of that sword is your father. I will tell you more about it if you can hold that blade".
Hiroto is in shock at the reveal of his lineage, he put this matter in the back of his mind and started moving toward the blade with anxiety.
Hiroto held the handle of the blade with both his hands and felt no discomfort, he bent his knees and started pulling the blade out from the ground.
...
Brutus watched the events unfolding before him with interest, he saw the blade budge a little at Hiroto's first try so he prayed Hiroto doesn't pick up this blade.
...
Hiroto felt the budge so he put everything into it and started again, he felt no movement for a few moments. "I won't give up, you remind of me my father holding you will be like him watching my back. He started on the path to making himself a legend in the world but he failed his promise to you. I will tread the same path and stand at its zenith. I will conquer all the hurdles I will face with you in my hand, I will strike down everyone who threatens the safety of the ones I love. And you are a hurdle. I have to conquer, I will conquer " Hiroto said in his inner monologue.
"Ahhhh...." Hiroto roared and slowly the blade started coming out, outside dark clouds started forming with lightning streaks in the sky.
"Good the name of the katana you are holding is Onimaru, the books here contain your father's techniques along with his personal journal. Kaimana is the one who answered your summoning so she will be your personal summon. Inform your loved ones and come here, it will take upto a year for you to master all of them. Kaimana leave him in Konoha" Brutus said and left quickly. If anyone could see Brutus after he left there one could see tears in his eyes, "That blade has bathed in the blood of nearly millions since the thousand years it has been in existence and everyone who held that blade will walk a very dangerous path to die young or become a legend. Hiroko, I couldn't save you but I will die before your son could share the same fate" he mumbled seeing the building and left the vicinity.
...
Hiroto returned to Konoha with Kaimana along with a new addition. He returned to his backyard from where he disappeared, he quickly noticed Itachi and Anko there.
Itachi and Anko also rushed forward and enquired if everything is all right, Hiroto assured his friends everything is alright.
Soon all eyes turned to the new addition in Konoha. "Guys she is Kaimana, Kaimana this is Itachi and Anko" Hiroto made the introductions.
Itachi liked his friend's summon animal, Anko hugged Kaimana tight and bombarded the latter with a ton of questions. Sometime later "Hiroto summon me after you are done" Kaimana disappeared in a puff of smoke, not specifying the details as she knows Hiroto should be the one to do it.
"So what's with the new sword?" Anko asked.
"It used to belong to my father, it is safely stored in the summoning realm" Hiroto answered.
"Hiroto, Hokage-sama asked for you to meet him after you returned" Itachi informed his childhood friend as it's not proper to make the Hokage wait longer.
Hiroto nodded and left toward the Hokage building tying Onimaru to his hip. Itachi and Anko also tagged along.
...
Hokage building
The former Team 3 arrived at the Hokage building to see their sensei leaving the building.
Shikaku looked at Hiroto and breathed a sigh of relief as he is worried about his student even though he knew he would be alright. Hiroto recounted how Kaimana took him and he also said he need to talk to Shikaku about something later.
Shikaku invited his students to a meal in his house and left, Hiroto told the Hokage's assistant of his purpose and noticed her admiring look when looking at him.
Hiroto found this odd and didn't mull this issue further soon he was granted entry inside.
As soon as Hiroto entered, Hizuren looked up from his piles of papers spread around the desk. Hizuren gave a smile and signaled to wait a minute.
Hizuren then looked at Hiroto who is patiently waiting, "Sorry Hokage's duties". "It's okay Hokage-sama" Hiroto said in reply.
"You know you call me Grandpa Hiroto" Hizuren said with a smile.
"You're in the Hokage seat now so I should give the respect a Hokage deserves" Hiroto replied.
"Ok, I heard you went to the crocodile summoning realm" Hizuren probed for details.
"Yes Hokage-sama" Hiroto said and gave him a report on what happened, keeping all the books in that building a secret only mentioning his father's legacy.
"It's good, I see you also got your father's sword" Hizuren said eyeing the sword.
