big question is there any bl or gl isekai stories?

These two I can think at the top of my head that are in some sort of webcomic form at the moment:

http://www.mangago.me/read-manga/to_be_or_not_to_be/ (bl)

These two are adapted from a webnovel and there is other webnovels that are gl and bl isekai stories.

Not exactly a BL but the gay tensions are high (๑•ㅂ•)و✧
