Kaori Mizuhashi
Kaori Mizuhashi is a woman who's already hit 40. Yes, you heard me right, things can get rather misleading, but...yeah. She sounds REALLY young, most of her characters sound very cute (IMO, the archetype where she excels in), and she can do a huge variety of voice types. Once again, she has been in the industry for quite awhile, so her resume speaks for itself. She does a tsundere well with Minami (Baka Test series), and she can also sound cute with girls like Norma (Tales Of Legendia), Meiru (Rockman Exe Series), Fel (Prism Ark), or the overly energetic Marona (Phantom Brave). She can also do a very convincing young boy voice with the super badass kid Laharl (Disgaea Series), another character she nails out of the park. Then, there are my 2 favorite characters from her, Yagyuu (Senran Kagura) and Ougi (Monogatari Series). Yagyuu showcases her kuudere voice and Ougi is just a mixture of...weird cuteness. She's a complete enigma of a character, and Mizuhashi's voice portrays her excellently.

Ryoka Yuzuki
All hail Kiryuin Satsuki. Ryoka Yuzuki is also another woman who's been in the industry for quite awhile...some of her characters can start to show their age. Yet again, this is another seiyuu who's somewhere around 40 is still presently voicing over high school characters....yeah. Let's get the big ones out of the way first, most importantly, Kiryuin Satsuki (Kill La Kill). This is one of the most powerful and impressive female characters I've ever seen in an anime, and props to Ryoka Yuzuki for showcasing such a powerful voice for such a powerful character. Then, we have girls from older franchises: Ino (Naruto Series), Aruceid (Tsukihime) and Reala (Tales Of Destiny 2). Ino and Aruceid are teenage-y, high school-ish characters who sound attractive enough, while Reala is a young girl, so its only normal that she sounds cute. Risa and Celine (To Love Ru Series), while from the same franchise, sound super different, one's a playful, seductive girl, the other is simply a tiny mandrake baby girl. Then she's got the troubled high school teacher in Shizuka (My Teen Romantic Comedy SNAFU), and the tough as nails, naughty school girl in Akio (Trinity Seven).
Characters from left to right

Satoshi Hino
This guy's got the voice of the protagonist in him, and its easy to see that he's got quite a few of those roles down just right. He's got the voice of righteousness, reckless teens in him, he takes the cake with roles like Yuji (Shakugan No Shana), Saito (Zero No Tsukaima), and even a character like Hamazura (To Aru Majutsu No Index II). Then he can be a little bit shy or loud with a character like Kinjiro (Mayo-Chiki) or Enigman (Sket Dance)....who is an excellent example of a combination of both loud and reserved. Then, he's got the occasional cool guy demeanor with someone like Sai (Naruto Shipuuden), who's actually pretty badass, or a character that goes full YOLO like Iwaizumi (Rail Wars!). My favorite character from him is one that he did rather recently, and that's Isaac (Log Horizon). While he does well doing the younger, high school student age characters, I'd like to see him do manlier, more bold characters like Isaac...Satoshi Hino can sound downright intimidating if he wants to.

Houko Kuwashima
Well....its Kasumi. That's all you need to know really, here you go, the seiyuu of one of the sexiest fictional characters to ever exist. Houko Kuwashima is one HELL of a versatile, veteran voice actor. She's got plenty of tricks up her sleeve, and she's one of those girls that you can never tell from in an anime or game where she voices in. Its almost impossible to know what tone of voice belongs to her...just because her range is THAT massive. Anyway, the obvious one is Kasumi (Dead Or Alive), who's just a squealy, sexy kunoichi with a rather high pitched voice. Then she can go quite low with characters like Isara (Valkyria Chronicles) or Presea (Tales of Symphonia), the latter is almost a kuudere character archetype. She can do boys (evil ones too!) with Shion (Darker Than Black II), or a somewhat serious girl with Cyrille (Shining Force EXA). Slightly more mature ladies like Rebecca (Shakugan No Shana III) or Medusa (Soul Eater) are right down her ally too, and she can go super cute-sy with a girl like Vivian (Cross Ange).

2nd row: Rebecca (Shakugan No Shana III), Cyrille (Shining Force EXA), Medusa (Soul Eater)
3rd row: Kasumi (Dead Or Alive Series), Isara (Valkyria Chronicles)
Toshihiko Seki
Old dude with a bisohunen voice, once again, this is probably a trend that you'll notice in the seiyuu industry. Toshihiko Seki is....over 50, and sounds amazingly fabulous. If I were to compare him to another seiyuu, it'd be Koji Yusa, both sound fabulous for their age. Seki does well with the more bishounen characters...the tall, dark and handsome ones. The ones that he voices with said tone are Aleister (To Aru Majutsu No Index Series), Warrior Of Light (Dissidia Series), Embryo (Cross Ange), and so some extent, even Kogoro (Project X Zone). He can, for some godly reason, voice younger characters like Loni (Tales Of Destiny 2), and do very well at that. He also has the nicer guys like Iruka (Naruto Series), or the completely random, serious, blood sucking sailor uniform in Senketsu (Kill La Kill). My favorite character from him however, is Sanzo (Saiyuki Series), is badass monk from an anime that's considered pretty old school at this day and age.
