Author's note: This series is my homage to the manga and anime series, "Baki the Grappler". Yes, I know there are about 3 different mangas and, I think, 2 different animes with different titles, but I'll just call the whole thing "Baki the Grappler". So, meet Bachiko. Any resemblance to the original work in terms of characters, plot and theme is entirely intentional. I hope fans of the series will enjoy my homage!
IMPORTANT NOTE: The original character Baki is 13 years of age at the beginning of the series. Bachiko is a 19-year-old girl. Previous chapters included a note here placing her age at 21 β that is by the conclusion of the series. Within this chapter, she is 19.

Hanayama Kaori shrugged off her bathrobe to bare her upper torso.
Kaito's throat went dry as he struggled to control his reaction to this behavior. True, he had already changed his perspective of what it meant to be a "woman", but he still had to get used to how all these fighting women were so comfortable with nakedness. It was as if for them, everywhere was an onsen, and every day was onsen day.
Countless men had endured nosebleeds and painful bucket impacts on their heads to catch a glimpse of attractive women in the hot springs. He knew he was unreasonably lucky and enviable. But he still wasn't quite used to it.
And he was aware, if he displayed any impolite reaction... this girl was the Yakuza Princess. Never mind his relationship with Bachiko β his very life would be over within minutes.
But Kaori didn't even look in his direction. She extended her right hand in Bachiko's direction, and for a moment Kaito thought she was challenging Bachiko to an impromptu contest.
Instead, Kaori slowly clenched her fingers into a fist. She held it there, for some seconds, while Bachiko's eyes narrowed, and suddenly widened.
Kaori smiled. "Impressive! You've already noticed it? Truly the daughter of the Empress Hanma Yuriko."
Bachiko smiled. "You are the impressive one. I see it now."
Kaito blinked. All he saw was Kaori stretching out a fist in Bachiko's direction. What had Bachiko noticed?
"It's very kind of you to show me in this way, Kaori-san. It wasn't something I could observe properly when I faced you in the Arena."
"Naturally! When I am in the Arena, all my muscles are already pumped up and ready for exertion. Here, you can see what I am doing much more clearly, because my muscles are still in a relaxed state."
"Yes, I see that."
"Would you like to explain it to your boyfriend, Bachiko-san? He looks completely puzzled," Kaori laughed.
"How would I presume to do the explaining, Kaori-san! I am here as the student today," Bachiko modestly demurred.
"Very well, then, forgive my presumptuousness," Kaori chuckled, and addressed Kaito directly. "Kaito-san, you know the basics of how muscles work?"
"Um... uh... sure! Muscles contract when pulling, all movements are actually pulling movements..." Kaito said uncertainly. This had never been his particular field of study, but he had picked a few things up from having Bachiko as a girlfriend. "A movement is created when a pulling muscle, also known as the agonist, contracts, and another corresponding muscle, the antagonist, relaxes. This allows the movement to be done."
"A very rough explanation, but that will suffice. What about synergists?"
Kaito stumbled over the unfamiliar word. "I'm sorry, I... am not sure about that."
Bachiko spoke up. "Synergist muscles help to stabilize the movements of the agonist-antagonist pairs." Her eyes had lit up. "So that is your secret... that is the extent of your muscle control. Truly impressive."
Kaori's eyes glinted as she smiled. "Truly, the Hanma daughter. Nothing pertaining to muscles will escape your understanding for very long."
"You flatter me."
"Now let us explain to your boyfriend," Kaori said, not unkindly. She spoke to Kaito again. "When I clench my fist, which muscles are being activated?"
"Those in your forearm."
"Yet, look at my biceps." Kaito swallowed hard at that casual invitation. It was one of the most magnificent arms he had ever seen, and through these weeks he had seen some truly spectacular female arms. "Are my biceps not flexed right now?"
"Yes, but of course you are tensing them... I see! All muscles work together in a system... even when an ordinary person like me makes a fist," Kaito made one, "other surrounding muscles tighten as well! But... how is that the secret to your grip strength, Hanayama-san?"
