"Ow, ow, ow..." whimpered Kenshin Himura, as Megumi Takani applied some medicine to his recent wounds. He had recently defeated an extremely powerful enemy, but it had taken his ultimate technique, the Amaka no Hireiameki, to win in the end.
"Quit complaining. You ask for this everytime you use that technique," frowned Megumi, being a concerned doctor. "Your body is way too lithe and frail to withstand such stress,"
"Come to think of it, Sessha remebers master mentioning something about that," thought Kenshin. His master, Hiko Seijiro, had explained that the ultimate Hiten Mitsurugi no ryu technique was self-destructive in exchange for its immense power and speed. Seijiro, however, was able to prevent that with his enormous muscle mass, which was able to take the pressure with little, if any, harm.
Kenshin sighed, knowing there was no way he could ever gain such muscle himself. But he couldn't just stop using the techique. There were people he needed to protect, and the AnH had to be used in case of the extremely powerful enemy. But he was no good to anyone dead.
"Hmm?" blinked Megumi, before she grinned and gripped Kenshin's stomach a little. "Oh Ken-san...seems like you've grown a little belly here,"
Kenshin turned red and went, "Oh...well Kaoru-dono's cooking is getting better...slightly..."
"Careful or you'll become a big mass of corpulence," joked Megumi.
"Mass?" thought Kenshin, before it hit him. His body needed to get bigger to withstand the stress of the AnH, and if muscle wasn't an option, fat was!
