Hmm, what bromance relationship that you think was done really well?

I will update this list but right now I will be brief.

-Gon and Killua from Hunter x Hunter
-Luffy and Usopp (CP9 Saga especially)
-Luffy and Zoro
-Naruto and Sasuke (pre Sasuke retrieval arc)
-Ares and Mikael from Ares
-The Elric Bros from FMA
-Hiruma/Kurita/Musashi from Eyeshield 21
-Kira and Athrun Zala from Gundam Seed (this relation I like much better than the one from Code Geass)

to be continue.

My favourite "Bromance" relationships are those between

• Worick Arcangelo & Nicolas Brown from Gangsta. by Kosuke: A bloody cool gangster duo. Way to go, Benriya!

• Rensuke Isezaki, Yui Kurata, Uemura Naotaka & Souta Nogami from Seishun Kouryakuhon by AKIZUKI Sorata: A bunch of high school rascals and their adventurous everyday life. Brings back memories...

He can't understand that they end in him, but they don't end with him."

• Ursula K. Le Guin, Gifts[/color]

To be savoured:

• Blood Alone by TAKANO Masayuki
• Otoyomegatari by MORI Kaoru
• Gangsta. by Kohske
• Seishun Kouryakuhon by AKIZUKI Sorata

Since I just read 7 Seeds - Arashi and Ango
Sasahara & Kohsaka from Genshiken - The Society for the Study of Modern Visual Culture
Kimi to Boku ehh, the whole character's relationship is nicely done to me.

Ginji Amano + Ban Mido from Get Backers
Mitsuhashi Takashi + Itou Shinji from Kyou kara Ore wa!!, their relationship is really hillarious^^

Any bromance in Eyeshield 21 and Ookiku Furikabutte.
