Summary
Shinkawa served as a prominent member of the notorious red guild «Laughing Coffin» and wielded the «Estoc Thorn Sword», which was uniquely bathed in a crimson hue. He harbored a deep resentment toward Kirito and the other clearers who had dismantled «Laughing Coffin» during the anti-PK raid. Operating in tandem with Johnny Black, the two formed a deadly partnership focused on poisoning and murdering their targets.
