Cojo Recommends: An Evil Dragon That Was Sealed Away for 300 Years Became My Friend · 5:36am Aug 10th, 2021
Okay, I don't normally do this, but this manga is so cute I just had to show you guys.
This was a Twitter manga that's apparently getting a serialization at some point, though, I can't find anything about that. The plot, such as it is, as according to Mangadex is:
Youta wanted a friend, so obviously, he magically summoned one. He didn't quite count with the fact that he'd summon Mumu, a mighty and evil dragon girl, notwithstanding that due to hundreds of years of imprisonment, she's very needy, very weepy, very clingy, and lonelier than the button "9" on a microwave oven.
But, honestly, there isn't a plot, really. It's more of a slice-of-life anthology about the main pair with no overarching storyline, though I wouldn't put it past the serialized version to have something grander going on.
Don't be turned off by the girl on the cover, this is not a hentai. Just some sweet feel-good aaawwwwwwws.
