It has been 2 months since Ichika was discharged from the hospital, and as of now, he is currently practicing chakra control. After exercising and being ready to use the chakra, he couldn't do it well, even though the chakra control on the system said 20%; he couldn't, so he had to relearn.
This relearn doesn't take long, only having around 2-3 days of practicing and he is again able to do it now.
He learns his lesson and doesn't dare to try learning Six Path Jutsu until he has enough chakra. No, he didn't, he still wanted to try it out.
When his sister heard about how he got into a coma, she was just speechless, well didn't tell her the Six Path Jutsu but used other Jutsu like Fire Release: Great Fireball Jutsu. Technically speaking Great Fireball Jutsu doesn't require much chakra and to compensate for this lying he added that he was trying to change its shape and kept practicing without realizing it.
If one looks at it, it is quite easy to know that this is a lie. A good lie needs some truth to it, and since he already learned Great Fireball Jutsu from his sister, he can use it.
Even with his sister, he still uses his code of never sharing a secret even if they found it out; he would try to eliminate them if possible but if not he'd let them go.
Don't love your enemy, they are the cause of your problems, if not then you're the problem.

After being able to use chakra again, he immediately began his ridiculous training. Oh, he met Might Duy about 1 year ago, but since Duy was usually training in his home.
Might Duy was a part of the Second Hokage plan of the Eight Gates, he didn't learn the Eight Gates because Duy said that he hasn't mastered it, and he doesn't want to teach an imperfect version.
Ichika respects Duy's decision and he doesn't press into it. Ichika learned most (60%) of his exercise plan came with the help of Duy.
Because Duy was in his mid-20s and also because he had a wife and also his yet-to-be-born son. He has been trying to take as much of the D-Rank mission as he could to raise the income he can bring in.
Ichika met Duy's wife before. When Ichika met her, he could say that she was average but a bit slightly more than average.
In the original series, there was no explanation of Might Guy's mother. Most of the characters' parent are skipped and that kinda leaves a plot hole, but it's okay as the creator wasn't focused on the family; was more into the ninja themes.
…
Ichika doesn't train with Minato or Kushina as they have their own specialty. Kushina needs to train in Sealing Jutsu, she's trained by Mito as Kushina needs to be the next Jinchūriki, whether she likes it or not.
Minato specialty in speed and reactions. His training consisted of throwing kunai and tracking where they would go. He met Sakumo Hatake while training.
Ichika doesn't know when they knew each other but he did have some ideas from it.

"Duy, how have been doing? Haven't seen you for a while" Ichika was doing his usual run.
"I have been taking a lot of missions and you know my wife currently is pregnant" Duy was a bit tired as he had been running and doing missions all day.
"Should I help out, you don't want to collapse when multitasking" Ichika was offering a real thing, he didn't want to play a trick. "I'm not taking anything, I need experience, I'll be graduating in 3 months from now"
"I guess you can. Thank you" Duy is a humble guy and he doesn't want to owe someone.
"Alright, I'll come to find you tomorrow, I have to keep my youth," Ichika said as he kept on his run.
"Yes, power youth never fail!"
