An Evil Dragon That Was Sealed Away for 300 Years Became My Friend (Pre-Serialization)

Yaki Tomato

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. A serialization now exists, though the chapter numbering is not straightforward. Twitter raws can be found in the URL below. Pixiv raws (which update after the Twitter release) can be found here.
