Hi, sorry that the title is so vague.

I'm looking for a particular manga that I read a while back but can't remember the name of. The tags I remember are shounen, fantasy, tragedy, comedy.. It's about a boy(protagonist) who's pretty much useless but gets this superpower with which he kind of grows dragon wings(not flesh wings, more like sci-fi robot wings with magic miasma around them). He joins this guild and in the first chapters he actually fights against members of it(although they were not bad dudes)- they were escorting a slave-carrying vehicle while the protagonist and company had to stop them. He has a female friend who is a vampire(there was something about the ability to turn everything into gold, but I'm not fully certain) and whose arch nemesis is the villain of the manga- some rich guy who eventually gets the main character to die a heroic death which saves everybody. There was this character who teams up with the antagonist- he has a childish body(as far as I remember) and is also a dragon. There was also one invisible character who was actually a dragon himself. It's a short manga.

All help is appreciated, thank you!

i put shonen and fantasy in genre, and put dragon in categories.

i get

Fire Emblem - Hasha no Tsurugi
Stealth Symphony
Archlord

are any of this what you want?

Well, I'll be damned. It's Stealth Symphony. Thank you! I'm sorry I'm a cretin who doens't know how to search properly.

Once again, you have my gratitude!
