300年封印されし邪龍ちゃんと友達になりました

Synopsis

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](https://mangadex.org/title/ff09caa3-a990-4dff-a22f-d33d9be38f1c/300-nen-fuuinsareshi-jaryuu-chan-to-tomodachi-ni-narimashita), though the chapter numbering is not straightforward. --- Twitter raws can be found in the URL below.
