Also known as: 雑賀孫市
A playable character in the Sengoku Basara series, starting with Sengoku Basara 3. She is the leader of the Saika mercenary unit, a band that focuses exclusively on firearms. She wears a two-piece dress that exposes her midriff, including an asymmetrical skirt, and has a collection of revolvers strapped against her right thigh.
The name Saika Magoichi may possibly be an alias or title, as Chousokabe Motochika refers to her as Sayaka. This is a bit of Voice Actor Connection as Ohara Sayaka is her voice actor.
