YuY是流著眼淚笑著的表情，期望能在不怎麼美好的世界裡帶來一點讓人會心一笑的插畫創作。作品中總會出現的生物是一隻叫神秘狗的兔子，是個在身旁默默支持與陪伴的存在。

YuY is a smiling face with tears, hoping to bring some moments that make people smile through illustration creations in this not-so-beautiful world. A recurring character in the works is a bunny called Mystery Dog, who quietly supports and accompanies those around.
