Hisao Egawa also voices both Goemon and Yoshihiro, with both their voice tones also being notably different; Egawa also voices a Dynasty Warriors character as well.
Also applies to Kanetsugu and Kanbei/Kanbee (Masaya Takatsuka).
The calm and jerkass Mitsunari and the silent yet hot-blooded Katsuie (Eiji Takemoto).
Both Hanbei/Hanbee and Aya (Umeka Shouji).
Kojuurou and Kagekatsu are voiced by Ryouta Takeuchi.
Katsuyuki Konishi as both Toshiie and Naomasa; he's also not very different from Ryoutarou Okiayu (along with Hideo Ishikawa and Hisao Egawa as aforementioned) in that they have three-to-four different roles so far across the whole Warriors/Musou franchise.
Dueling Games: With Sengoku Basara. Musou is a lot more down-to-earth and grounded when compared to Basara, but it has more international appeal and makes it more clear that it's geared for everyone, when Basara lately likes to hit it with the Yaoi fandom, this is shown with how Musou likes their fair share of women, while Basara likes to insert a lot more Ho Yay. To make this more apparent, both games also has some sort of "competition" of including their officers, if there's a character who was exclusive for Musou, it'll only be a matter of time until Basara adds their own rendition (and vice versa). To note, at least on the Musou side:
Sanada Masayuki was announced Sengoku Basara Yukimura-Den before he was announced for Samurai Warriors Sanada-Maru (the same installment that completed the Sanada family for both series)
And like Basara, starting from possibly 2 Xtreme Legends, but more blatantly since 3, Musou has also started including their 'archetypes'/'semi-Expy' based on a Basara character, usually a different character representing the same 'clan', and usually differing in characterization. Sometimes.
Gracia (debuting in Samurai Warriors 2 Xtreme Legends) is usually meant to be the 'representative Christianity character' to go with Basara's Pontiff Xavi (debuting in Sengoku Basara 1). This is the only occasion where it's continued in another Basara character: Ootomo Sourin (replaced Xavi since SB3).
Kobayakawa Takakage (debuting in Samurai Warriors 4) is the 'Kobayakawa representative' to go with Basara's Kobayakawa Hideaki (debuting in Sengoku Basara 3).
Koshoushou (debuting in Samurai Warriors 4) is the 'alluring Cloth Fu lady' to go with Basara's Kyogoku Maria (debuting in Sengoku Basara 4). This is the only one that didn't have anything to do with clans but more 'play-style'.
No Export for You: Sengoku Musou 3 Z, Sengoku Musou 3 Empires and Sengoku Musou Chronicle 2nd.
Gina Bowes voiced Kunoichi in the first game, and would return to the role in the third game. This makes her the only dub VA for the series to return for not only another game, but the exact same role.
