Rurouni Kenshin Chapter 234: "On the back of the man Part 7- "The Meaning on His Back"
Thanks to Francis for the comment below!!! Which basically leave you drooling for more, but there it is.
Well that was a kinda neat ending to the Sano side story. He
found his
smile, beat the living snot out of 200+ people, and got Kaoru another
potential student. Although, that makes what? Three? Yahiko (the only
one
actually present), Yuutarou (if he ever shows up again), and Outa (expected,
if he ever gets rid of those ANNOYING SHINY CHEEKS!!!! HE LOOKS LIKE A
RAGDOLL!!! KOROSU!!!!!!)
You want scans? Kenshin's Rurouni Resource Centre has 'em.
