Goyou (This appears to be a name or a word requiring more context for accurate translation)

serious, sweet, slightly hostile, naive, curious, might hit you

They wear monochrome clothing; their outfit consists of a black shirt with small ruffles, long sleeves, a high collar, and two silver inverted crosses on the front, as well as a long black skirt with a grey belt. They also wear a short cloak that fastens over the shirt. They have fairly short, straight black hair, pale skin, and dark eyes. They are presumably carrying some kind of weapon, which Agape describes as "sharp and pointed." Goyou has two small black wings on their back, which are indistinguishable from bat wings and apparently unusable. They are childlike and naive, asking many questions and showing particular interest in people's lives and emotions. Despite this, they are silent if they have nothing to ask and often don't understand jokes or teasing.
