William Massachusetts

'''"Meetings are boring and useless. I want to walk my own path!"

- William, Volume 2 Annex '''

William Massachusetts, also known as Eyes of Mystery William, is the guild master of Silver Sword guild. He was invited to be a member of the Round Table Alliance but declined, stating that its goals had nothing to do with him and his guild.

Personality
William dislikes joining meetings as he opposed his guild's joining into the Round Table Alliance, preferring to "walk his own path." However he encourages the remaining 11 guilds to work on the current problem, proving that he's against joining the alliance but not against their principles.

Apocalyspe
William was seen rallying his guild right after the Apocalypse.

Resolve
William appears at the beginning of the episode as Shiroe explains how Guilds work. Silver Sword is mentioned by Maryelle as one of the guilds that was aiming to reach level 91 along with the Black Sword Knights.

Round Table Conference
William is one one of the guild masters who is invited to the Round Table Conference escorted by his elite bodyguards. However, he leaves shortly after the conference begins because he feels that the situation in Akiba isn't something that his guild, which is a battle guild, should care about.

Even though he doesn't personally want to be involved in improving the conditions in Akiba, he encourages the remaining guilds to continue working on the problem in his absence (he is against the Silver Sword participating, not against the idea in principle).
