Hamada is a rogue servant of Matsunoshin Gohda known to wear glasses.
In Rikimaru's story, he learns that Hamada is in on Tokubei Echigoya's plan to sell girls into slavery. The ninja then sneaks to Gohda Castle and cuts down Hamada before any harm could be done to Gohda.
In Ayame's story, Hamada takes Gohda hostage and demands the Jewel of Virtue from him. Ayame finds the rogue retainer about to cut Gohda's throat. It seemed like she would let him go, but the kunoichi frees Gohda and fights Hamada, killing him. Later, Tenrai's voice booms from Hamada's corpse.
