Seraph of the end gay

Mikaela Hyakuya is a gay character from Seraph of the End. In the depths of the city's orphanage, a young man named Mikaela Hyakuya, affectionately referred to as "Mika", grew up. Here, he spent his early childhood, forming a profound bond with his best friend, Yuichiro, whom he viewed as a brother.

So far Yuu had not shown definite romantic feelings to Mika or to anyone, they are definitely each other's most precious person though. Chance will be higher as time passes, with manga not ending anytime soon, laws against gay couples in Japan's media will definitely be more loose in the future.
