Jiraiya used the Summoning Jutsu, so a big cloud of white fog appeared. Usually, the size of the cloud is proportional to the size of the one summoned. Ryo expected something of the scale of Gamabunta or Gamaken.
âJiraya Chan! You can summon me directly now, it seems like your Sage mode has improved greatly!â The smoke has not disappeared yet, but an old voice could be heard within it.
âBoss!â Hearing the voice in the smoke, Jiraiya was shocked.
âHuh? Youâre not in sage mode?â
The smoke dissipated and a palm-sized green toad stood there in front of everyone.
âFukasaku Sama! How come itâs you?â Minato also went to Mount Myoboku, where he got familiar with the two great sage toads.
âMinato, this feels awkward, whatâs with all the respect? This one isnât that big!â Asked Kushina.
âMount Myoboku is one of the big three unexplored Sage regions. There reside the conscious Toads. They have three elders: Gamamaru sama is the patriarch, and his two heirs who are the two great sage toads: Fukasaku sama is one of them, and heâs Jiraya Senseiâs trainer.â
âMinato Chan! Stop whispering.â Fukasaku had centuries of training. His perception was amazing, and he could hear everything said by Minato, even though he was merely whispering.
Embarrassed, Minato scratched his head.
âMinato, who is the other elder?â Seeing that Fakasaku wasnât angry, Kushina asked Minato to finish his answer.
âItâs his wife, Shima Sama.â
Fukasakuâs temper was much better than Shimaâs. It was fortunate for the bunch that the one summoned was him. It wouldâve been a lot of trouble if Shima heard Kushinaâs comment about her size.â
âThen Jiraya Chan, seeing how youâre surprised, I can suppose that youâre not the one who summoned me?â
âTrue, boss! This is the kid who did.â
âWhat?!â Fukasaku was extremely confident about his perceptive abilities. But he was not aware of the existence of someone behind him.
He turned around, looked at him, then closed his eyes and tried to perceive him. But what happened surprised him.
What he perceived in Ryoâs position was a block of Ice.
This was the 1st time Jiraya saw Fukasaku be so amazed. âBoss, this kid is called Ryo Yamanaka. He is a new contractor.â
âRyo Yamanaka?â he looked well at Ryo.
âYes, boss! Originally, I also wanted to go to Mount Myoboku to talk with you about him.â
âOh, whatâs the matter?â
âHereâs the thing. I found out that this kid can use Jutsus that are ice-related. And he was using natural energy!â
âHow could this be? Ryo Chan, can you show one of those Jutsus?â
Ryo nodded and froze Water Waves he created.
As Ryo did that, Fukasaku didnât perceive that Ryo was using a Ninjutsu, he actually perceived Ryo turning into a part of nature.
Even in Sage mode, one just absorbs natural energy, merging it with physical and spiritual energy. Ryo creating the ice didnât involve any use of Chakra.
âJiraya Chan, where did you get this contractor from? Heâs able to use pure natural energy perfectly!â
âBoss, you mean that the kid didnât use Chakra at all while freezing the water?â
âThatâs the case.â Fukasaku was positive about what he was saying.
âWell, how come, Fukasaku sama, that every time I use Ice Release, I consume a lot of Chakra?â Ryo was wondering.
âChild, are there any conditions you should meet before entering this mode?â Fukasaku took a while before answering.
âYes! I must be in a special mode, the one thatâs active now.â
So Fukasaku nodded and carried on asking: âThan you need to learn how to maintain this mode without spending Chakra!â
âI donât need Chakra for that. Once I get into the mode, I donât spend any Chakra to maintain it. Itâs just that freezing requires huge amounts of it.â
âAha! So thatâs this case! Ryo Chan, your mode is perfect, but the problem is with you.â
âIs there a problem with my use of natural energy?â
Ryoâs biggest trump card was Ice. If he can solve the problem heâs having with ice requiring huge amounts of Chakra, even his fights with Kushina wonât so one-sidedly dominated anymore.
âIt not your use of it thatâs the problem. Fixing your problem requires more than understanding natural energy. It is the energy that circulates in the world. In your mode you are a part of nature itself, you energy is part of natureâs energy, so you can maintain this mode without consuming any more energy.â
âSo Fukasaku sama, why do I lose so much chakra whenever I try to freeze anything?â
âItâs very simple, Ryo Chan, when you use any Ice Release Jutsu, you actually consume natural energy from a close source, with the closest being yourself! When youâve consumed all-natural energy in your body, the flow of energy is passively supplemented with your chakra to maintain your ice mode. Thatâs how you drain your Chakra.â
With Fukasakuâs interpretation, Ryo finally understood it.
When using his Ice element, Ryo was like a pool thatâs full of water, with 2 inlets and 2 outlets. When Ryo is in his Ice mode, itâs like having one of the inlets and 1 of the outlets open. This keeps the pool full and prevents it from overflowing. For Ryo, it maintained the amount of natural energy within him stable.
Using an Ice release Jutsu opens up the second outlet within him without opening the 2nd inlet, making water (natural energy) leave his body with incredible speeds. Here, to maintain the fullness of the pool, he needs to use his reserve water source, his own Chakra! Once itâs over, the pool is drained and he canât use Ice Release anymore, nor could he use normal Ninjutsu as he has no more chakra.
If he keeps on using Chakra to supplement his consumption of natural energy, even having a Biju shouldnât cut it.
âFukasabu sama, there any solution to this problem?â Ryo asked.
âYes, learning how to replenish natural energy consumption from the universe is the best way toâ¦â
âBoss, do you mean to learn the Sage mode?â Jiraya also asked.
âJiraya San please let him finish!â Ryo glared at Jiraya.
âWell, itâs the same concept. But unlike other practitioners, you donât have to worry about being swallowed up by natural energy as he can become a part of nature. Itâs just thatâ¦â
He looked in Ryoâs eyes, hesitated a bit then said: âYou can never use Sage mode!â
