After I engaged with Hanabi. Many months already passed. While I am practicing in the morning. Raphael sent me a message.
[Host magic powers reach elite jonin level]
"Oh, Finally. Raphael use magic card" I said.
[Yes,Host]
Then I feel it.My magic powers greatly increased.
[Host magic power reach Kage level]
"It's time to go back to Ryuchi Cave" I said.
'Reverse Summoning Jutsu'
-Boom-
"Ho, So you are ready now" White Snake Sage said.
"Yes,please"I replied.
"If you fail I will eat you,you know that?" She asked.
"I know but I want more power" I said sincerely.
Then White Snake Sage came and bite me.
-Chuck-
Then I feel greatly pain all over body.
[Detect strange energy inside Host body]
'It's f**king hurt. Raphael control and balance my energy.
(In this world mc magic powers used as chakra)
[Yes,Host I will take action immediately]
After sometimes passed I didn't feel pain anymore.
"Ho, so you didn't just succeed but also complete master it, huh" White Snake Sage said.
I pick up a mirror in my inventory and look at myself.
I have red pigmentation around my eyes and have yellow irides and slit-like pupils.I also gains a purple chakra shroud that forms into ethereal snakes around my body.
(His body didn't change much like Kabuto and Mitsuki because he didn't using a bodily reaction exhibited by members of Jūgo's clan like them.He attended it naturally.)
'Damn I am so cool' I think.
"You have passed the test then now I announce that you are officially contractor of Ryuchi Cave" White Snake Sage said.
"Thank you very much.White Snake Sage then I will excuse myself first" I said.
'Reverse Summoning Jutsu'
-Boom-
I appeared at my home.
'I have Raphael that can absorb natural energy and balance it so I can easily attend Sage mode and maintain it. thank you so much Raphael' I said in my mind.
[You can already rely on me,Host]
I walk out of my house and see Hanabi ran in my direction.she jump and hug me tightly.
'What' I think.
"You didn't come at morning. We thought that you are just late but stil you didn't come so we went to in form Hokage Sama and he sent people to find you but didn't find you" Hanabi said.
'Sh*t I excitedly so much that I forgot to inform anyone' I think.
"I worry about you so much. Why are you suddenly disappeared?. Baka!! , Idiot!!" Hanabi cried out.
I inform an anbu that I am safe and will go to find my master then I said sorry to Hanabi many time and comfort her for a long time.
"Let's go to master office" I said.
"Yes" Hanabi just nod.
-Hokage Office-

"Sorry sorry I made you all worry" I apologize to them.
"It's okay. You are safe that is importance thing" Konohamaru said with a smile.
"Yes yes" Moegi agree.
"The thing Konohamaru said it's true but I need to asked where are you Shiki Kun" Master said.
"Well I go to Ryuchi Cave, Master" I said.
"Why are you go there Shiki Kun" Master asked.
Then I showed them my new power.
