Heck, even The Adventures of Dr. McNinja has one! And that comic has almost no love/sexual references at all. It's right here, in case you want to see it. And, ladies, you do. The Fanservice is even lampshaded in the Alt Text, which reads: "Lil' bit of fan service for you ladies out there." It's much-appreciated, Doc Hastings. Very much appreciated.
All too frequently in Goodbye Chains, much to the pleasure of fangirls.
Very recently, The Phoenix Requiem had one from Robyn...while he was splashing around in a stream...covered with authentic battle damage. It was entirely justified (he needed it to scoop water with) and the female readers are not complaining.
The artist apparently had a small internal argument with her Robyn-muse.
Sarah: I need some way for Robyn to get a lot of water up there, the fat shade is too big to be broomed. Robyn: I could use my shirt. Sarah: Don't be silly. Maybe there is a bucket lying around or something. Robyn: Yeah, that wouldn't look like a convenient coincidence AT ALL. Seriously, I could take off my shirt and use that. Sarah: That's fanservice! I need to not do that! Robyn: It's not fanservice, it's LOGIC. (takes shirt off) SHIRTLESS O'CLOCK! Sarah: * sigh* ;_;
This scene from Harkovast, where Ki first appears. Mind you, the Ano-Chee and Junlocks never seem to wear shirts at all!
In DMFA, Abel remains shirtless about 85% of the time.
In Abel's Story, it's played for laughs:
Mink: (grinning)...Oolong got your shirt again.
Abel: BUGGERING HELL!
Juathuur: a short but nice shirtless scene for Ratheel and Dejoru starts Here. One for Thomil can be found Here. (warning: spoilers!).
