attributes.description: en 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.

attributes.description: es Youta quería una amistad, así que *obviamente* usó magia para conjurar a una.  
    
  No contó con el hecho de que conjuraría a Mumu, una poderosa y malvada niña dragón, no obstante que debido a cientos de años de aprisionamiento ella es **muy** necesitada, **muy** llorona, **muy** pegote, y mas solitaria que el botón "9" de un horno microondas.
