Willem Kmetsch

Willem Kmetsch is a male character of the SukaSuka series.

Former Quasi Brave, a group of warriors that serve the church along with the Regal Braves. He was known as the strongest of the Quasi Braves.

Willem was petrified/frozen 526 years ago, before the seventeen beasts appeared and less than a year before humanity went extinct.

Last human known to be alive 527 years after humanity went extinct. He was stone-frozen a year before it, under the age of 16. His resting-curses have been lifted 2 years before events take place.

Likes to play with kids (after growing up at an orphanage), although some mistake it for "him being into little girls".

Some might say he is over 500 years old, but as per definition of age/-ing (process of getting older) and from the LN, he is to be recognized as 18.

In the light novel Willem's status is deceased, but in the anime the status is still unknown. It is because the scene of Willem in the anime is stoped right after Chtolly said thanks.
