Police Chief Uramura had confronted Kenshin at the Kamiya Dojo during lunch one day to ask if he could assist in the capture of a serial killer named the Kurogasa. The Kurogasa was only killing high ranking officials of the Meiji Government, so Kenshin took the offer. The next place the Kurogasa was to strike was a man by the name of Tani, whom Kenshin knew from the past when he was the Battousai. Sano had tagged along for no reason, he just wanted to fight. Midnight struck and the screams of the policemen were heard outside. Expecting the murderer, Kenshin, Sano, and a bunch of hired swordsmen awaited his arrival, but suddenly were paralyzed.

The Kurogasa made his appearence. Before he could begin killing anyone, Kenshin revealed that only he was not paralyzed. Leaping from behind Sano, Kenshin had tried to strike down the Kurogasa in one hit, but ended up only cutting his hat. Both men looked at each other and recognized their alternate identities. The Kurogasa was a Hitokiri of the Shinsen Gumi whose real name is Udou Jin'e, and of course, Kenshin was the Hitokiri Battousai. Jin'e wanted to fight the legendary Hitokiri after waiting for such a long time. To start off, he used the Shin no Ippou paralysis technique. That did no good, as Kenshin already demonstrated he could not be affected by it.

Sano somehow shook off the Shin no Ippou, grabbed a statue, and swung it down at Jin'e. With ease, Jin'e sidestepped, but Kenshin wasted no time beginning a swordfight with the Kurogasa following. Kenshin and Jin'e were an equal match up until the time Jin'e found an opening and cut Kenshin's left arm slightly. Disappointed, Jin'e left the scene, demanding that Kenshin change back into the Battousai, rather than a non-killing rurouni, and fight for real for their next encounter. Without the Kurogasa's presence, everyone else was freed from the Shin no Ippou.
