Alef has a big ego and thinks he is more mature than his cousin, Nabla. He is very passive-aggressive. He also puts on a nice guy act, but will snap when tampered with. He is easily irritable, as seen when he's called "Aleph", his real name, which he deems a dumb name. Though he often gets into many fights with his cousin, he does seem to at least care about her, despite their many conflicts and arguments. Alef's teasing of Nabla could be playful and fun and games in his mind.
