Artificial Spirit: Holly (ホーリエ).
The fifth Rozen Maiden doll and the first to appear in the series. Her name, in addition to its Japanese meaning, could be also a play on the Japanese pronunciation of the word "cinq" (French for "five"). She embodies the traditional Victorian aristocrat. She is extremely demanding and can seem unappreciative of others. Her favourite words are "tea", "servant" and "What?" She seems to enjoy lecturing, slapping, and generally abusing Jun, her medium, at every opportunity. She is perceived as rather angry, but it is a façade that she puts up to show that she feels that she is most deserving of becoming Alice. Shinku is also perceived as being cold, but she is actually very protective of, and cares deeply for, her sisters and for Jun. Shinku's presence at the Sakurada home has led to other Rozen Maidens appearing there. She hates cats because one almost swallowed her wind-up key in the past.
In combat, Shinku fights with rose petal-based attacks. The rose petals are extremely versatile; Shinku can direct them to spread out for wide-ranging attacks, or group them together to use as a shield. Her other weapon is a cane, which she skillfully wields like a sword. Shinku has other special powers, such as restoring broken objects, typically Jun's bedroom windows after Suigintou's bear/clown jumps in, and when Suiseiseki shows up, with a form of time-reversing magic. Shinku was the most powerful doll in Rozen Maiden series.
