Kakashi was gobsmaked when he saw wood style. Sure he has seen wood style but that was from a person implanted with Hashirama cells. This however is the True wood style through and through.
Kakashi looked at Ryu: How long have you had wood style?
Ryu: For more than a year.
Kakashi seemed to think for a bit before saying: You passed. From now on you are a Genin. Come with me, we need to report to the Hokage.
Ryu nodded. They both went towards the Hokage's office. Sarutobi was having a rare break from the mountain of paper works. He laid back on his chair, taking small puffs from his smoking pipe. A knock came from the door breaking his mood. A women came in and saluted Sarutobi, she reported
' Hokage sama, Kakashi Hatake has come with his Genin to report '.
Sarutobi nodded and sent her away. He thought ' Haha, Kakashi must have had a shock seeing how strong Ryu is. Sigh...Ever since his teammates death he has been isolating himself. This ought to have jolted him a bit '.
The door to his office opened, Kakashi and Ryu came inside. Kakashi's figure was a bit ragged and he looked tired. Sarutobi grinned seeing this, after all it's not everyday you get to see that deadeyed kid this exhausted.
Sarutobi: Looks like Ryu was quite a handful.
Kakashi: Hokage sama, your joke was not funny at all. You could have atleast warned me about his strength. The test was meaningless for him.
Sarutobi laughed: Intel gathering is essential for a shinobi. Just because he was a graduate, you let your guard down and this was the result.
Kakashi was annoyed seeing the Hokage like this. ' Laugh while you can. I really want to see how you react to what I am about to say '.
Kakashi: Hokage sama, there is something important I would like to report.
Sarutobi tilted his head in confusion. Kakashi continued: Ryu can use wood style.
Sarutobi froze. His pipe fell off his mouth. His mouth was soo open you could fit a fist inside. Kakashi was smiling brightly under his mask, he had his revenge. Sarutobi came back from blanking out
Sarutobi: Can you repeat that?
This time it was Ryu who answered: I can use wood style.
Sarutobi again froze for a few seconds before he snapped back. He looked at Ryu with a wry smile. ' This kid is giving me one surprise after another '. Don't be mistaken, Sarutobi was happy that someone finally emerged who was able to use wood style.
Sarutobi looked towards Ryu : How long since you were able to use wood style?
Ryu : A bit more than a year.
Sarutobi analysed, only a Senju could possess would style. Its like kekkei genkai for them. So the question is, how come Ryu possess their kekkei genkai? This doesn't make any sense.
Sarutobi had many questions, he asked Ryu about the situation when he awakened wood style. Ryu had already prepared a cover story for this
Ryu explained : Old man, do you remember me telling about me having inherited memories. Well...as I finished learning all the seals, I got another memory.
That memory showed me that, the first Senju and Uzumaki had the same origin. As in..they were children born from the same parents. This is my take on how I got the wood style based on my memories and some theories.
My bloodline is the purest of all the Uzumakis, it's equal to the first Uzumaki. As my bloodline is so close to the origin of both these bloodlines, somehow my body was able to tap into the hidden Senju strength. Atleast that's what I think.
Sarutobi thought for some time. He knew that Uzumakis and Senju were blood relatives but that connection was never traced back to its source. If what Ryu said about the first Senju and Uzumaki being siblings is correct then there is a possibility of either of the bloodline acquiring certain aspect of the other clan.
Sarutobi inhaled a long breath, he sorted out all the information and decided to believe what Ryu said. Anyway Ryu will never harm the village, so it doesn't matter how he got the wood style. Sarutobi told both of them to report here tomorrow to receive their first mission. As Ryu is someone on the same level of Madara and Hashirama, Sarutobi has already chosen an apt mission for him.

The next day
Ryu got up, he was about to do his morning routines when Navii gave him a surprise
Navii: Master, the mission tab is online.
Ryu quickly checked the missions tab

Ryu saw many missions which included saving the Jinchurikis from dying, saving Nagato, killing black zetsu, removing Kaguya's control over chakra etc etc. Some of them have very hefty rewards.
Ryu got dressed up and went to the Hokage's office to receive his first mission from the Hokage and to complete his first from the system. He waited beside the office for kakashi to arrive. Unlike his usual laziness, Kakashi didn't take long to arrive. They both greeted each other and went inside.
Sarutobi was not alone this time. Shikaku was also with him discussing the arrangement for the recent graduate Genins. Shikaku saw them come in, he took a scroll from the table and handed it to Sarutobi.
Sarutobi : Kakashi, you should now know how strong Ryu is. Due to him just graduating, I can't just promote him straight to Jounin. So, I have selected a mission for the both of you.
Saying upto here, he tossed the scroll to Kakashi. He opened it and read. His face changed showing surprise.
Sarutobi : Your mission is to go to the land of water and hunt a rogue ninja who has fled there. The description of him as well as his known abilities are detailed in the mission scroll. Do you accept this mission team Kakashi?
Kakashi: Yes.
Sarutobi: Good. You will leave in two days. Off you go.
With that said he sent us out. After Ryu went out of the office, Kakashi said goodbye and told him to meet up at the village entrance in the morning in two days.
