Don't worry—Ky Kiske is very heterosexual.

The very first page of the Isuka Outlive Encyclopedia has a super homoerotic poem and it's awesome. I originally had it on my porno comix archive page but that can't be linked to in polite company. So here it is on its own page.
Click to enlarge. Thanks to Bocchi The Rock FGC for the crisp scan.
skuldydrabble, who did the scanlation of the doujinshi above this, did a translation of this poem into English:
Hostility is akin to love
Thinking of your opponent's actions to fight
Reading your opponent's inner thoughts to fight
Planning attacks that will hit your opponent to fight
And then transmitting your thoughts with those attacks
The more you think of your own advantage, at the same time you think of your opponent
In the instant you mix with your opponent, a passionate feeling arises, and blood boils
Reality is hurt, and you wound your opponent
Hostility is akin to love
The doujinshi not the guy.
If you liked this poem you might also like "Christ" doujinshi by the Serenade circle (Yuu Shizuki), from 2004 and scanlated by skuldydrabble in 2008, with additional credits going to doctorskuld and asphodel. It has implied sex but nothing too graphic.
