Minato's regret before becoming Hokage and that he is unable to save his students. Minato wants to save Kakashi from his death-seeking behavior. Everyone tried to bring him out of the darkness but it didn't bear fruit. Minato consulted Hizuren on this and his predecessor advised him to arrange Kakashi in the security detail of Kushina.
Kakashi returned to Konoha a few days ago after his mission failure and had another brush with death. Kakashi started to loathe himself every time the one he is supposed to protect will be the one to lose their life. Kakashi is now making his way to the Hokage office after receiving a summon from his sensei, the only remaining family he has. "I can only distance myself so you or Kushina-nee or Hiroto don't suffer because of me Sensei," thought Kakashi and opened the door.
Minato had a solemn face seeing his remaining student brooding. "Kakashi from here on you are gonna join Anbu protecting Kushina," Minato said with a straight face. It took a few months to bring about a gradual change in Kakashi, his student is again starting to open up but he isn't completely out of the shadows yet.
Minato and Kushina are afraid Kyuubi's seal might break during childbirth, so he together with Kushina is in the process of developing a new seal. Minato thanked his brother-in-law for some of his fūinjutsu notes that he left behind which helped them speed up the process.
Minato and Kushina also taught Hiroto and Itachi fūinjutsu during those days. The Yellow flash and his wife are in awe of Hiroto's talent in fūinjutsu, Itachi is considered average in fūinjutsu but their talent is reversed when it came to genjutsu.
Minato also tried to teach the kids Flying thunder god jutsu at the first level but Itachi had to give up since there is no progress. Hiroto surprised everyone when we developed his own Flying thunder god jutsu seal with the help of a shadow clone. Minato helped Hiroto with kunai to use that jutsu proficiently, Hiroto chose the same design as the Yellow flash but with a blue handle.
Hiroto after applying his FTG seal gave kunai to his parents and his best friend. "If you had them with you when you're in danger I can come to rescue you." Hiroto said giving those kunai's which made everyone laugh and his cheeks hurt so hard that day courtesy of Kushina.
Minato being a very good sensor himself taught kids some basics, for Hiroto he had to teach more since his son is also a chakra sensor. Hiroto also can sense people around five feet radius but when he tried to push the limit he feels dizzy and blood comes from his nose. Minato and Kushina had given him an earful that day.
After Kushina's baby bump started to show up both her husband and son did all the chores around the house without giving her any choice. Previously she went to Mikoto's house when she didn't have a noticeable baby bump but later it isn't possible courtesy of her jinchūriki status.
Mikoto also couldn't visit her because she is ready to give birth within a month or so. Due to this Itachi and Hiroto became messenger birds for their mothers.
Minato one day returned home to see "Hiroto how will take care of your younger brother ?" asked Kushina while gently rubbing her baby bump. "But how do you know the baby is a brother but not a sister ?" Hiroto asked Minato's thoughts aloud.
"Because I'm the mother" Kushina answered ruffling Hiroto's hair. Minato also made his presence known to them.
"I will help in raising my brother" Hiroto declared.
"Yeah, it will also help Hiroto to raise children when he became older" Minato said his thoughts without thinking. Hiroto shuddered and took a step back after looking at his mother, noticing this Minato can only curse his stupidity.
"My baby Hiroto you should make mother happy. I will help you find a girlfriend for you when you are older, it would've been better if Itachi had a twin sister. Don't worry Mom will help teach you how to impress a girl. Hahahah.. by the time your brother becomes a ninja you will make me a grandmom, right ?" Kushina said with a predatory smile.
Hiroto could only nod meekly and turned his eyes away and gave Minato an angry look. Minato could only look the other way feigning an innocent look. Minato is lucky people are scarce in the surrounding areas or he might have to look at mad witch is back in Konoha complaints.
Minato became the youngest kage in history which brought along high expectations of him. Minato cursed his predecessors for making Hokage a paper pusher.
An intruder made his way to Hokage's office through the window. Minato know only one person who uses this way so he smiled fondly and called the person "Sensei."
Jiraiya looked at his student surrounded by a mountain of paperwork. "Minato how are things going?" the toad sannin asked his student.
"Everything is going pretty well Sensei " answered the young toad summoner.
"Good I've heard from toads that you've also learned sage mode." Jiraiya said.
"Yes, sensei a perfect sage mode the toads said" Minato took a jab at his sensei and patted himself on the back that he did it before becoming Hokage, or else he may've had to wait for several years.
Minato invited Jiraiya for a meal at his place and also made a shadow clone to make prepare dinner and inform Kushina.
Jiraiya followed Minato to his home, after they opened the door the sannin noticed Kushina with a big belly and a red-haired kid by her side. Jiraiya doubted whether the kid could remember him as he met the kid a few years ago.
Minato arrived a few moments later changing his attire and bringing a book along. Noticing the book Hiroto sat by Minato. Jiraiya made small talk to Kushina about her health.
Minato saw Hiroto looking at the book and placed his son on the lap and read it together.
After a few minutes
"Oh, you're reading 'The Tales of a Gutsy Ninja' huh?" Jiraiya said looking at the book.
"Yeah, it's one of my favorite books sensei." Minato replied.
"But it didn't make any money." muttered the book's writer.
"Sensei I want to name our son Naruto." Minato asked Jiraiya if there are any objections. He is pleasantly surprised by his student's decision. "That makes me quite happy Minato, this makes me the kid's godfather huh?" Jiraiya expressed his joy. The room is full of smiles with that.
"So you wrote the book Uncle Pervert ?" Hiroto asked enthusiastically.
Jiraiya looked at Kushina admonishingly while she can scratch her head looking away. "Hiroto his name is Jiraiya, he is my sensei. You can't call him that from now on" Minato reprimanded his son. The long white-haired shinobi can only sigh and answer "Yeah my first book".
"So Can I read your other books ?" Hiroto expressed his desire.
Every adult in the room froze. Before Jiraiya could respond he felt heavy killing intent directed at him. Kushina's hair started swinging wildly defying gravity and slowly came towards Jiraiya.
That day Jiraiya suffered his second near-death experience and ironically both at the hands of women.
