Tsunade was quite open-minded about it.
"Apprentice early, finish early."
"Here, this is my gift for taking a disciple. On one side is my medical handbook, summarizing most of my medical knowledge. On the other side are the essential ninja tools a medical ninja should use from age six to eighteen. In short, a medical kit."
Tsunade opened the box in her hands. Just as she said, everything inside was related to medical treatment.
But when Gekko Chizan looked at that stack of notes—and the little money symbols drawn on them—it was obvious at a glance that this was handwritten by Tsunade herself.
"What are you looking at! I like money. So what if I draw a few bills?"
"Do you want it or not? If not, I'm taking it back!"
Sensing the amusement in Gekko Chizan's eyes, her face flushed slightly red.
These were all accumulated bit by bit during her time as a medical ninja. As for the money symbols… well, she really did like money.
"Of course I want it. How could I not?"
"Pakura, bring Senka out to meet her future teacher."
Hearing that Tsunade had arrived, Pakura was quite happy. She walked out carrying the just-one-year-old Gekko Senka in her arms.
"Here, my daughter. Pretty, right?"
Ever since Gekko Chizan had children, he had become a full-fledged doting parent.
At first, he spoiled Gekko Dōnin.
Later, he spoiled Gekko Senka.
"Senka, this is your future teacher. See how generous she is?"
"Oh, right, Senka, remember this—your teacher is rich. To prevent her from wasting her money, when you grow up, you must help her spend more of it. That way it'll be good for her!"
Gekko Chizan reached out and poked Gekko Senka's chubby little face.
The moment he finished speaking, Tsunade's face darkened.
Even Pakura couldn't help but laugh. In the end, although Gekko Chizan had matured a lot, the mischief and clever cunning in his bones hadn't diminished in the slightest—if anything, it had only grown stronger.
"You bastard, Chizan! Your heart's getting darker and darker!"
"That's my gambling fund!"
If not for Gekko Senka being present, Tsunade would've really wanted to teach Gekko Chizan a lesson—though chances were she wouldn't even be able to touch him.
After all, Gekko Chizan's Flying Thunder God specialized in evasion.
"Tch. Gamble, gamble… why not just be a proper doctor?"
"With your ability, just treating a few big shots would make you plenty of money, wouldn't it?"
"Come on, Senka, let's take you as an apprentice."
At that moment, Gekko Senka displayed an unexpected reaction.
Seeing Tsunade, the little girl in Pakura's arms stretched out her tiny tender hands, trying to grab her, joy shining in her eyes.
"Huh? Chizan, your daughter seems to really like me."
"Hahaha, come here. Let your sensei hold you."
Tsunade adored the little bundle of flesh in front of her.
She took her future disciple from Pakura's arms and held her close. There was no denying the destructive power of a baby—especially against adult women.
Looking at Tsunade now, it was hard to imagine she was the legendary Tsunade-hime renowned throughout the shinobi world.
"Hahaha, Gekko Senka, from now on you're my disciple."
"Your sensei will definitely raise you to be outstanding—better than your damn bastard father!"
Gekko Chizan's face darkened as well. Fine. So we're going with mutual damage, huh?
Gekko Senka giggled happily in Tsunade's arms.
Then something happened that shocked all three of them even more.
As she laughed, her body began to disappear little by little. The sight stunned Tsunade.
"Chizan, what's happening to Senka?"
"Transparent Release! Hahahaha! I knew it! My daughter has awakened my Transparent Release!"
Gekko Chizan's hearty laughter shot straight into the sky.
Transparent Release—the vanishing Gekko Senka right before their eyes had awakened Transparent Release.
Erasing one's presence and rendering the entire body transparent.
This had been one of Gekko Chizan's greatest assets in carving out his reputation. Once Transparent Release was activated, no matter how heaven-defying your abilities were—I would simply disappear!
"Not bad! Hahaha, very good!"
"Pakura, we're going out tonight. Barbecue. We have to celebrate!"
"I—... What? Damn it, Tsunade, back up! No—wait, use chakra to isolate yourself!"
Gekko Chizan was dancing with joy when he suddenly sensed a faint fluctuation.
That tiny ripple startled him.
Because he was far too familiar with this chakra structure—it belonged to Crystal Release.
In a hurry, he could only shout for Tsunade to quickly isolate herself from Gekko Senka using chakra.
Though confused, Tsunade did as told. It was precisely because she listened that she avoided a small disaster.
Crack...
A crisp sound rang out from Tsunade's arms.
Immediately, a pink crystal appeared around them.
The moment they saw the crystal, Tsunade froze.
Pakura froze.
Even Gekko Chizan froze.
The first two were stunned by the appearance of Crystal Release.
The latter was stunned by its color.
"This is… Crystal Release?"
"Mm… it really is Crystal Release…"
When the crystal shattered, Gekko Senka's figure reappeared in Tsunade's arms.
However, a trace of exhaustion showed on her tender little face.
A one-year-old child simply didn't have enough chakra to support the use of two kekkei genkai.
In that short moment, her chakra had already been completely drained.
"Waaah!!!"
Her crying instantly echoed out.
Well then—chakra overconsumed. She was hungry.
"Senka, come here."
Pakura hurriedly took Gekko Senka and walked inside, leaving Gekko Chizan and Tsunade staring at each other.
"Tsunade, you hit the jackpot."
"Mm. I'm definitely taking this disciple. But Chizan, why is Senka's Crystal Release a different color from yours?"
Gekko Chizan was pondering the same question when the system spoke up to explain.
[Ding! Host, no need to overthink it. Your Crystal Release is a product of the system. Although it can be inherited, after inheritance it returns to its original nature. Only the host is special.]
[Ding! By the way, the original color of Crystal Release is pink!]
Hearing the system's explanation, Gekko Chizan actually felt quite satisfied.
What made him more curious, though, was Transparent Release. Would it also differ from his?
[Ding! Transparent Release is inherited entirely according to the host's version—isolating presence, ignoring chakra perception, and rendering the entire body transparent.]
That's more like it. Transparent Release is what really matters!
Transparent Release is the true king.
Crystal Release is merely support.
