First person: I (polite) Second person: -san (honorific) He took a woman named Maria to the restaurant where they had their first date and gave her a hat with a blue line as a birthday present. Kazuma was so happy he decided to wear it forever—in the bath, while sleeping, and during meals. Maria told him to wear the hat and go to the forest with her. Kazuma felt as if a weight had been lifted from his soul. However, as they finished their meal, Maria suddenly looked pained and collapsed. The next day, the doctor told him her time was short. She had a severe heart condition. From there, Kazuma was manipulated by a scheming Blue Umbrella and became a monster. He uses the blue umbrella to fly.
