So,... imma skip directly to chunin exams! Though I will tell what happened in the 5 months!
1) Sakura's chakra level surpassed Chunin and entered Jonin level, thanks to @crackcultivation.
Using 5 clones, which surprisingly didn't made her tired and overloaded, she finally completed intermediate level of sealing and entered the advanced level.
She now has four D-rank and one C-rank genjutsu.
Basic Three.
Water Clone, Shadow Clone, Multi-Shadow Clone.
Fire: Fireball Jutsu.
Earth: Hiding in a mole, Head hunter, Earth Punch(Covering arm with earth)
Wind: Nothing
Water: 1000 water senbons(Self created), Waterball Jutsu
Lightning: Nothing
Rasengan (Secret: Not in use)
Shadow Senbon Jutsu(Shadow Shiruken Jutsu Rip-off)
5 gates. Super Punch, Superkic
2) Naruto is focusing on Chakra control, doing the waterfall exercise he did in Shipudden on advice of Sakura. Other than that, taijutsu and Wind nature transformation. He is close to completing it.
(In Shipudden, he was 16, and he is 12 here. That's why it is taking him so much time even with shadow clones.)
3) Sasuke activated sharingan when trying to dodge Sakura's senbons. She has learnt to control them to be not insta-killers. The event will be explained later in some flashback.
And since I hate Sasuke, I am not going to describe anymore about what is happening in his life.
4) Kakashi is enjoying Icha-Icha. He is pleased that he doesn't have to put much effort in teaching Sakura. He just gives her some scrolls, performs the jutsu and she tries to learn it by herself. Naruto doesn't ask much for jutsu as he is busy with chakra control and nature transformation, and Sasuke... well he is Sasuke so I don't want to explain.
So anyway, I am going straight to Chunin Exams, and will cover the important things in the next volume, which will be between Naruto and Naruto Shipudden.
So, let's meet next time!
