Kizuna

One of the most popular series, you know, and also one of the best. Kizuna was published in 1992 and is still running. At the moment there are 8 volumes and the mangaka is Wohl Kazuma Kodaka. Well her style isn't that soft and it also is a bit more to see, but there are a lot of fans, and so it's still quite popular! Kizuna is also a manga, I would say it's Yaoi, cause it's not that "hidden" (ah... I'm not english, how should I explain ^^). So I would say Kizuna is a manga for adults. Beside the mangas you can find one artbook and 2 OVAs. 

The first OVA was published in the year 1994/95 and has 2 parts, the other one was published this year, only some month ago (march 10th).All in all Kizuna is recommendable, but only for adults, because kizuna is really Yaoi ^^; Yaoi and Shonen Ai Fans should talk a look at this "oldie"... it's quite a good one.

A short message about the plot: Enjouji and Ranmaru are good friends and know each other since highschool. But afterwards they seperate and meet again in upper school. Because of Enjouji cool and distant behaviour Ramaru thinks that his old friend isn't interested in their friendship anymore. Enjouji on the other side tries to be away from him, cuase he fell in love with his friend, and won't destroy his friendship...

Of course the two became a couple... the story above is a flashback in the mangas, I only use it as a small introduction (ähem ^__-)... but there are still enough things you'll get to know, when you buy the manga ^^;
