Oh man, Shirota's not exactly my area of expertise, but I shall do my best!

First things first: his wiki page, his dwiki page, and his wiki.theppn page; his profile, his blog, his brother's blog, his brother's band's blog. *is not a stalker* Okay maybe a little. (For relevance, said brother is also a jewellery designer; he designed the matching necklaces Shirota, Jin, and Pi all own, if I'm remembering right.)

Fun with YouTube!
He's a giant dork. (slkghdlskh Tuxedo Mask, lookit him swish that cape!)
He can sing like woah. (He wrote the song too, as a challenge for DD-Boys, which is probably the crackiest, coolest show I've ever seen.)
He brings the fanservice! (Retarded fanservice too!)
He can be serious on occassion! (Okay, serious-as-Tezuka, but the point stands.)
Frighteningly serious... while singing about tennis. (I cannot emphasize enough how much I love that video. *SPAZ*)
His English is utter FAIL. ("Perfect racket in all of the world!" I'll bet he and Jin have wonderful conversations in broken English. ♥)

*EXHALES* Uh, that's it for junk I have bookmarked. Is that a solid start?
