Affiliated with Aoni Production for a long time in her career since 2002, Shiraishi Ryouko has a rather vast repertoire of roles up her sleeves, with a considerable number of young male characters among her usual mature, caring oneesan-type characters. Though Ryouko is more known for her various female roles such as Onizuka Hime in Sket Dance, Nishio Rina in Soukyuu no Fafner, and Anew Returner in Gundam 00, she is also known to be good in voicing effeminate, kind bishounens.

Shiraishi’s alto voice is incredibly gentle, the young man type of sexy, which probably also what scored her a role in the first all-female seiyuu otome game released in 2004, Goes!, in which she voiced Vince Vivian Vickers. Her most known male role is probably Ayasaki Hayate of Hayate no Gotoku, as well as Wanijima Akito and Agito of Air Gear, which showcased both Shiraishi’s cute feminine voice and her brash boy, but violent one, and also Schrodinger in Hellsing Ultimate.

Matsumoto Rica’s voice is probably the most known in the world out of the rest of the seiyuu in this list, thanks to her trademark “Pokemon, getto da ze!” line. Not to mention that other than working as a seiyuu with permanent recurring roles in popular series, she was also a member of JAM Project. In the long, long years of her career, she is known for her brash and powerful voice befitting protagonist roles—for example of course, her role as Pokemon’s Satoshi, and let’s be real, there are countless of girls out there crushing on Satoshi.

Her brash and strong voice makes for a great dangerous, sexy antagonist role as well. A good example would be Bakura Ryou from Yu-Gi-Oh, Mitarai Kiyoshi of Yu Yu Hakusho, or Nataku of CLAMP’s popular series, X. Matsumoto Rica was also the voice behind Matsuno Choromatsu of the old Osomatsu-kun series. Sadly, it’s rather hard to find Matsumoto Rica’s voice in anime series nowadays other than the ongoing Pokemon series, though she had just reprised her role as Bakura Ryou in the newest Yu-Gi-Oh movie.

With an impressively extensive repertoire of male roles, Sanpei Yuuko is best known to voice young cheerful boys who are straightforward even if they are sometimes annoyingly loud, such as Gintama’s Seita, Uzumaki Boruto in Boruto: Naruto the Movie, Kadoya Masamune in Beyblade: Metal Fusion, and Harima Shuuji in School Rumble. Yuuko is one of the few female seiyuus who is more popular for their male roles instead of female ones—though she does voice girls as well—take Yumehara Nozomi in Yes! Precure! 5, Yoshida Chizuru in Kimi ni Todoke, or Machi Youko in Bokurano.

Depending on the male characters she voices though, when she gets calm, mature, and cool male characters, Sanpei Yuuko’s voice could turn charmingly sexy in your ears. Older female anime viewers might remember her portraying Saionji Kanata in Daa! Daa! Daa!, which charmed everyone with his cool but rather careless personality. There was also Akizuki Ryou of IdolMaster DearlyStars, the bishounen Afuro Terumi in Inazuma Eleven, Satou Shinya in Mitsudomoe, Yuzuru Ema in World Trigger, and Ryuu in Akagami no Shirayukihime.

Despite being known mostly for her successful female roles such as Midorikawa Nao in Precure All Stars, Yoko Littner in Tengen Toppa Gurren Lagann, and Miyamoto Rei in High School of the Dead, Inoue Marina’s most known role is actually one of her male roles: Armin Arlelt of Shingeki no Kyoujin. Affiliated with Sigma Seven, Inoue Marina has been doing various kinds of roles ever since her debut in 2004. Among the male roles in her repertoire are Tagiru Akashi in Digimon Xros Wars, Inugami Koutarou in Mahou Sensei Negima!, and Hazama Hikaru in Beyblade: Metal Fusion.

Having a rather versatile voice, though her range doesn’t reach as low as the other seiyuu mentioned in this list, Inoue’s light but upbeat voice proves to be a cute kind of sexy in some particular characters. One of her notable roles, Tachibana Wataru in Hayate no Gotoku, definitely managed to steal a lot of people’s hearts. Don’t forget to check out her voice in Grand Stage, an all-female seiyuu otome drama CD, where Inoue voices Kazamiya Eru.

Looking at someone from 81Produce this time, Takayama Minami is the owner of the voice behind the all-time classic series Detective Conan series’ Conan Edogawa and Kudou Shinichi. Her performance in this anime series has always been amazing, considering Takayama has to switch to her lower ‘Shinichi’ pitch every time she voices Conan’s inner monologue. She’s also widely known to have voiced Tendou Nabiki in Ranma ½, Rantarou in Nintama Rantarou, and Ascot in Magic Knight Rayearth, and Kiki in Ghibli’s Kiki’s Delivery Service.

She might have done only several female roles, but they are all considerably amazing: Anissina von Karbelnikoff in Kyou Kara Maou! and Kati Mannequin in Gundam 00 are some of them. Takayama’s voice is the kind of light, almost playfully sexy, especially when she voices questionably antagonistic characters and draws out her dialogue. Take a look at Asakura Hao in Shaman King, Mithos in Tales of Symphonia, or even Dilandau Albatou in Escaflowne. She was also the one who voiced Envy in Fullmetal Alchemist Brotherhood, taking over the role from Yamaguchi Megumi who did him in the 2003 version of the anime.

Recent anime audience would perhaps know Minagawa Junko as the voice behind Ten’ou Haruka, or Sailor Uranus, in the new Sailor Moon Crystal. Male anime audience would probably recognize her as the voice behind Cornelia Li Britannia in Code Geass series. But Minagawa Junko is actually most known for her extremely low alto which had scored her many young male characters who are slightly sully, arrogant, or temperamental—most notably her role as Echizen Ryouma in Tennis no Oujisama.

Among her more boyish and less sexy voices in her roles was when she did Aoyagi Ritsuka of Loveless, Oz Vessalius in Pandora Hearts, and Kaidou Ren in Super Lovers. If Echizen Ryouma doesn’t sound sexy enough for you, do check her calmer roles in Duel Masters as Hakuoh, Asaba Yuuki in Kimi to Boku’s drama CD, or Saruwatari Shinobu in Godannar. Minagawa Junko was also cast in the otome game Goes! as Hinata Eli Farce. And don’t forget Trinity Blood where Minagawa Junko voiced the extremely beautiful Earl of Memphis, Ion Fortuna!

One of the very few Japanese seiyuu who is actually a fluent English speaker, Kaida Yuki actually started her career as a stage actress before becoming a radio personality and then a seiyuu, and is currently freelancing. Though her voice range is actually quite wide and versatile, Kaida Yuki’s known best for her young bishounen roles—beautiful, slightly mysterious young male characters, or mature, if slightly flirty oneesan characters such as Alexandra Garcia in Kuroko no Basket, and Jamille Kaela in Sister of Wellber. Along with several seiyuu in this list, Kaida is also another one cast in the all-female seiyuu otome game Goes!, portraying the mysterious and expressionless Kurone.

Kaida’s male voice range is pleasingly soft and almost whispery, sounding very tantalizing in your ears, almost playfully sexy. Her best male role, also known as her most notable role, is Fuji Shuusuke in Tennis no Oujisama. Other than Fuji, several of her rather sexy male roles you should definitely check out are Himura Kenji in Rurouni Kenshin: Reflection OVA, Riou in Saiunkoku Monogatari, Kurapika in Hunter x Hunter, and Asaba Yuuta in Kimi to Boku drama CD. She’s also the voice behind Makabe Masaki in Zettai Shounen, Abe no Masahiro in Shounen Onmyouji, and China in Hetalia series.

A veteran seiyuu who has been quite busy lately with her singing career, Ogata Megumi actually still does a number of roles in the voice acting industry. She’s the voice behind Ten’ou Haruka or Sailor Uranus in the original Sailor Moon anime, and has been in the industry for about 24 years now, most famous to voice many beautiful male roles in various hit anime. Her most legendary role is perhaps Ikari Shinji from Neon Genesis Evangelion and Himura Kenshin from Rurouni Kenshin anime series.

Ogata Megumi has a low, rather husky type of sexy voice that works really well with bishounen characters. Some of her sexy male roles include Yu Yu Hakusho’s Kurama, Tsukishiro Yukito or Yue in Cardcaptor Sakura, Sanada Yukimura in Samurai Deeper Kyo, and Dark Yuugi in Yu-Gi-Oh. Recently, she’s been doing roles for more boyish characters, and has been appearing in Persona 3 the Movie series as Amada Ken, Ansatsu Kyoushitsu as Horibe Itona, and Danganronpa series as Naegi Makoto. Ogata Megumi has also been casted as Hiou Akito in the otome drama CD Grand Stage.

Famously known as a Korean-Japanese voice actress, Paku Romi’s name leapt into absolute popularity worldwide ever since she began voicing the role of Edward Elric in Fullmetal Alchemist. Her voice is known to be strong if a bit rough, low and masculine, which secured her a lot of roles as young male protagonists or extremely tough female characters. Paku Romi won the First Annual Seiyuu Awards of Best Actress through the role of Osaki Nana in NANA, and she portrayed female roles such as Emma Guzman in Garo series, Teresa in Claymore, and Madam Red in Kuroshitsuji.

Other than Edward Elric, some of the roles Paku Romi is widely known for include Shirogane Naoto in Persona 4 series, Hange Zoe in Shingeki no Kyoujin, Ichijouji Ken in Digimon Adventure 02, and Natsume Hyuuga in Gakuen Alice. Her sexy voice is the rough, if a bit boyish type, which you could hear in her role as Bleach’s Hitsugaya Toushirou, Tao Ren in Shaman King, Regene Regetta in Gundam 00, Heimdall in Mythical Detective Loki Ragnarok, and Sengoku Basara’s Uesugi Kenshin.

If you look up Saiga Mitsuki on Google, one of the first suggestion you’d be getting is “Saiga Mitsuki’s gender”—a proof of how many people had been fooled by Saiga’s voice. Her repertoire is made up completely of male roles as well as manly, mostly badass, female characters. Some of her female roles include the cool Atari Kou in Star Driver and Maria Ross in Fullmetal Alchemist. She also gets a considerable roles of young boys, such as Okita Souji in Peacemake Kurogane, Shuu in Pokemon Advance, Kodate Mamoru in Soukyuu no Fafner, Tsukasa in .hack://SIGN, Wolfram von Bielefeld in Kyou Kara Maou!, and Rossiu in Tengen Toppa Gurren Lagann.

Having a naturally deep, masculine voice does give Saiga more masculine male roles than most other female seiyuu who voice male roles as well. Among the roles where she gets to sound sexy are Jing in Jing: King of Bandits, Jomy Marquis Shin in Terra E, MakubeX in GetBackers, and Robert Haydn in Law of Ueki. Saiga also has been casted a number of BL and otome anime, drama CDs and games—she voiced one of the Thanatos Kyoudai in Kannou Jikan, Nijou Sakuya in Norn9, Kai Jolis Sakura in Goes!, Suoh Yui in Grand Stage, and Hanashiro in Hana Ki Sou.
