A completely unhinged, bratty elementary schooler. He shares the same birthday as Michina, just a year apart. Although his real birthday is May 3rd, he claims he was born on June 6th at 6:06:06, causing confusion for everyone around him. He claims to drink blood, but it's actually just strawberry syrup. A gloomy boy with dark circles, a creepy smirk, and a severe case of chuunibyou, constantly performing curses and occult rituals. While he might seem like just a weird kid, he actually has a talent for curses; when he targets someone, it never ends as a joke. Ironically, he often ends up suffering the most from his own curses. Due to his gloomy aura and his obnoxious habit of muttering curses to himself, he is socially isolated in class, but he believes it's because he's special and superior. He has a peculiar way of speaking. He usually starts his sentences with "The great me~" or "This lord~" "Do you want a taste of the great me's terrifying power?!" He uses the above phrase quite often. He has black spiky hair in a two-block style, a fox-like face, and usually wears a shirt with short shorts. He is on the thin side. Due to an iron deficiency, his skin is pale and his eyes are sunken with dark circles. He constantly chews on iron nails in his mouth, which he can spit out with great force. He's quite good at it and uses them to snipe people when he's seeking revenge. He doesn't react to the opposite sex and remains indifferent even when looking at adult magazines—either he's truly uninterested or just too innocent to understand. Height: 159.8cm Weight: 48.7kg Age: 12 Gender: male Likes: Curses, shaved ice with strawberry syrup, attention. Hates: (Secret) People peeking at his diary, spiders. He occasionally uses 'The great me'.
