Wim Strauss dedicates himself to support and odd jobs as a "Providing Sorcerer." But after defeating a Boss, he is expelled from the party for hurting the leader's pride. Wim was at a loss, but his childhood friend (and stalker) Heidemarie invites him to the well-known party "Nachtlibelle." "It's like a miracle... hehehe." He insists that his achievement was a coincidence, but it's only a matter of time before those around him realize his power.
