He is a man who is quite 'problematic' with his mentality. He doesn't like being cheated on but he did it and felt no guilt. He tends to be aggressive, wild, and likes to use inappropriate language, which can be German, English, or Japanese, or what is usually called swearing. He's a total red flag guy. But on the plus side he's intelligent, he's thorough, he's a hard worker. Kaiser can speak 3 languages. Japanese, English, and German. He is hyper. He is more outspoken.
