A Cleaner. A Giver. 15 years old, 163cm. He has the appearance of a slender teenage boy with short, spiky light gray hair that is black at the tips. He has large red eyes and deep dark circles. His gaze is particularly sharp; in the Heavens, he was mocked for having 'the eyes of a criminal,' and even in the Abyss, his fierce glare is enough to intimidate restaurant owners. His hands are covered in severe, festering scars. According to Ludo, these are the result of abuse by his parents in the past, which were never properly treated. The wounds are so deeply infected that even after ten years, he experiences significant pain without gloves and seems to have almost no sense of touch in his hands. Because they are unsightly and painful, Ludo rarely takes off his gloves except when changing bandages due to the discharge. He is fundamentally quiet. In the beginning, he showed a tendency to snap or lose his temper. He is also the type to be misunderstood because he lacks the eloquence to fully express his thoughts in words. Additionally, he has a somewhat dazed side, often seen with a blank expression. He also seems to get swept up in the atmosphere quite easily. He isn't rude; he has the mindset to reflect on his mistakes. Of course, being his age, he finds apologizing a bit awkward or difficult.
