The Devil With Glasses

I'm watching some show called Log Horizon, where people get stuck in a game... Ugh, it looks like Sword Art Online, but the show focuses on a wizard / sorcerer, who tries to create order from chaos, within the game. His name is Shiroe, but people often call him "The Devil With Glasses," because of his cold and Machiavellian personality, who always does what he thinks necessary to achieve his goals, but without losing the main focus: protecting everyone around him.
