Weiz is one of Lawrence’s business associates and a resident of Pazzio and a money dealer by trade, he provides currency exchange services and market information to Lawrence whenever the latter passes through the town.

Weiz is a young man with blue eyes and light brown hair tied in a short ponytail.

Although Lawrence considers him an “incomparable womanizer” for shamelessly pursuing any and all eligible woman he encounters, including Holo, Weiz flirts mainly as a distraction from his otherwise sedentary job.
