Yuu Mori is one of the pre-made deceased ancestral Sims who resided during his lifetime in Riverblossom Hills, the neighborhood shipped with The Sims 2: Seasons. He was the husband of Hana Mori, the father of Kayami Wan, and the grandfather of Patricia Wan.
Yuu has personality points and interests, something not every ancestral Sim has. He is completely resurrectable, even though he doesn't have a grave. Yuu has the Popularity aspiration, and the Sagittarius zodiac sign. As far as personality, he is a very active, and quite playful. But he is very sloppy, quite shy, and somewhat grouchy.
According to Yuu's SimDNA in SimPE, his hair was red before it turned grey. According to his age data, he had 17 days left in the elder life stage when he died. Yuu's facial structure is seemingly identical to the 14th Maxis face template in Create a Sim.
