Mariko was the love of Logan's life. Logan fought Mariko's father Lord Shingen to prove himself, Logan lost. Logan returned a second time to prove he was worthy to Lord Shingen, this time Lord Shingen didn't survive. Mariko and Logan set a wedding date. Mariko was poisoned by Reiko with blow-fish toxin. Mariko's last wish was for Logan, her true love, to kill her with his claws, so she wouldn't have to feel the agony of the toxin killing her. Logan gave Mariko her request.
