Who Is Rin Asano?
Rin Asano is the only child of Takayoshi Asano, master of the Mutenichi-ryu dojo. The Itto-ryu, the rogue school absorbing dojo after dojo, came for hers: her parents were killed, the school destroyed, and Rin left as its sole heir with a moderate talent for the sword and an absolute refusal to let the matter rest. She does the arithmetic every revenge story requires and hires the one bodyguard who cannot be killed doing the job: Manji.
What makes Rin more than a client is that the series keeps auditing her quest. She begins naive, certain that vengeance is a clean transaction, and the nineteen-year run is as much her education as Manji's penance: the manga is, in its editor's words at Dark Horse, as much young Rin's tale as the immortal Manji's.
