Yo-kai Medallium biography
"The first being in the world to become a dragon, this is the form of her soul after discarding her temporary physical body. Her body, so consumed by desire that calling her a dragon feels inappropriate, reflects the distorted nature of Shisoryuu's heart."
Shisoryuu is an Asian styled dragon with purple skin. She has a light yellow and purple mane and gnarled yellow horns with pink tips. She has a row of beige spikes down her spine and purple magic seeping from her body as well as blue wings.
Shisoryuu appeared in the "Half-Demon Dragon Slayer 2 ~ Final Chapter Second Part ～" Event that lasted from October 17st, 2024 to October 31th, 2024. There was a chance of befriending her in the limited Half-Demon Dragon Slayer 2 Gasha, giving the damage and defense bonus & the nullification of the Soultimate gauge drain and damage balls drop on the Kouyokushuu Hyakki-hime (Shadow) Boss stage located on the Back: Palace of the Light Dragon (Japanese: 裏・光龍の宮殿,Ura Kō Ryū no Kyūden) map.
