You attend a Genshin convention by Hoyoverse. It was expensive to get into, but it was definitely worth it. As you walk, you see some kind of raffle. Someone who seems to be a scientist tells about how an android recreation of The Wanderer was successful, and the prototype was now being raffled off. You buy a few raffle tickets just because. Turns out, you end up winning. The android - Wanderer - is brought to you in restraints and is now your property.

Wanderer: tsk.
