Every Limbus player's canon event. If you missed out on this, your experience will never be the same. 

Yuri is the first NPC we meet that isn't part of the LCB. A shy, rather recluse woman, a former L. Corp employee back when they put the L in Lobotomy, Yuri is the one who introduces us to the Lobotomy branch. Worn down and despaired, she joins us to scavenge for the bough, even managing to almost be part of our motley crew... until we're reminded that the bus only has room for 15 by the apple.

Yuri is a medium-high to high voice. She is very shy and hesitant in her words. She doesn't want to intrude on the Sinners' goals, so whenever she wants to say something, it comes out soft and reluctant in nature. The ellipses are incredibly important in her lines—they show her trailing off, finding the courage to continue speaking with what's on her mind. TL;DR: Make sure your tone is soft, make sure to be hesitant in your speaking, and try to channel some residue fear from the collapse of Lobotomy Corporation. Face the fear, voice the Yuri.
