柚森
[yòu sēn]
'Yuzu Forest.' It could have two parts, 'Yuzu' as a fruit or character, and 'forest'. So it possibly means an imaginary or real scene where yuzus (a type of citrus) grow abundantly like in forest form, giving impression of tranquility and natural purity. Alternatively Yuzu can be Japanese girl's given name indicating it is likely chosen by fans from Japanese anime, games etc. for the endearment.
