Describe Hikaru Midorikawa here or I will kill you.

Hikaru Midorikawa is one of the well-known seiyuus in the business, though not as prolific (according to Anime News Network). He's most known for his distinctly cold voice, best suited for bishonen characters, which often lands him the roles of The Lancer, The Smart Guy, The Rival, Deadpan Snarker, etc. He occasionally breaks the routine, though, and goes along to voice silly characters just as good. But, seriously, even if he's voicing silly characters, there will be moments of angst for his character, so long as the character isn't completely a minor one.

Truly a Man of a Thousand Voices.

Roles comes very cheap. Especially Hikaru Midorikawa's.

(For some reason, the characters he voiced has a tendency to be cap tured and then restrained/tied up)

Though born in 1968 and already married, he manages other activities other than being a seiyuu, such as website managing (he's got one) and playing video games. Apparently, he's a big fan of Super Robot Wars, having a blog entry on the SRW site, contacts Banpresto and happily does extra lines for his characters (especially Masaki) for free, and usually becomes a beta tester for the games. He also have a habit to turn the characters he voices into one man armies in the SRWs (namely Heero and Masaki; he'll probably do the same to Xingke when he shows up in Z2, or Asakim in case he's recruitable)

He's friends with several other seiyuus like Ryotaro Okiayu, who also somehow shares a bit of his SRW passion (he voices Raidiese F. Branstein) and sometimes plays together. He was also a member of a music group with Nobutoshi Canna, but his greatest, most known relationship with other actors is definitely Takehito Koyasu. They often play roles that rivals each others, and Koyasu has once teased that Midorikawa's voice sounded cute; on the other hand, Midorikawa teased that Koyasu's voice sounded sexy.
