I'm looking for anime (prefered), or manga that's a shonen-ai adventure.
A kiss between the pair is a must. No yaoi!!!
Preferably if it's a longer series.

Something like Uragiri wa Boku no Namae o Shitteiru, or ABE Miyuki's Hakkenden or Komatta, or No.6, but with more kissing.

Search results for shounen-ai + adventure.

These are the ones I've read at least in part and can recommend, but as I recall there's little or no kissing, sorry. I'd like to see that, too. 😁
Gorgeous Carat - Kurayami no Bitoku
Koori no Mamono no Monogatari
Patalliro! - gag manga, the romance is with the side characters
Silver Diamond

I'm reading both Koori and Silver Diamond already.

I know that I chose a hard genre to find. (And I would love to see the animation of it. 😀 )
I guess it's such a niche that it's almost/totally non-existent.

You may have heard of Yami no Matsuei, since it's quite well known, but still: I'll leave the name just in case. It was on hiatus for over 5 years or so, due to the artist's hand injury. I think chapters are coming out again. The anime is awesome though. Short but worthy.

It's the Art of Time, it's the Art of Life--
Of the player and the craftsman,
Of the writer of songs, of the creator of love,
Of those who will follow, of those who led,
There's no other way in the world ahead ♥

Yup, you're right. I know it. I've already seen the anime back in 2011. But I've put the manga on hold. 😉

Mirage of Blaze - this is a little yaoish s*x scene only happened in the ova the TV series is shounen ai
Makai Ouji: Devils and Realist - this is only shounen ai but amazing its supernatural
Teikoku Kyoudai - it's shounen ai and about brothers
Kuroshitsuji - this is quite common it's only shounen ai and the master and butler has a very DEEP bond
Pandora Hearts - this is an amazing one i love this it's shounen ai too
Ilegenes - i love this manga to death it's so good and the 2nd season of the manga is ongoing which is Ilegenes - Giyoku no Koukyoukyoku

hope i helped 🙂
