Gin has the best eyes in bleach, hands down! the only time we see them is just before his death. Rangiku saw these eyes several times but us viewers didn't see them until just recently (recently if u watched english dub only)
Bleach: The first arc is epic. Awesome characters, amazing soundtrack and epic story. After the first arc it gets pretty crappy though and is full of annoying, boring fillers. I recommend watching the first arc, then dropping it.
I suppose that'd depend on whether by like you mean "Who do I want to be?" or "Who would I like to know?" Shizuo has a better personality, so I'd rather know him, but Izaya has information and a knife. I WANT TO BE IZAYA.
This is why I love going on Pinterest after watching a new anime. People agree on how Takeru looks like Kageyama and Haru, how gay they all are. VOJCE ACTORS THIS IS WHY I SHOULD WATCH SUBS INSTEAD OF DUBS. SERIOUSLY: BOKUTO, YOICHI, MIKAELA, SHIZUO, AND THE OTHER TAKERU SHARES I LOVE THEM ALL
