Berserker-class Servant who was introduced in the GUDAGUDA Shin Yamatai-koku event. Sen no Rikyu is known as a progenitor of chanoyu, or "The Way of Tea", in particular of wabi-cha which emphasizes simplicity. For some reason, Rikyu appears as a petite female even though Oda Nobunaga has always known him as a towering old man. Her third ascension is locked until players complete a Saint Graph unlock quest.
In actuality, she is an amalgamation of the grudge of people killed unfairly by Toyotomi Hideyoshi; which includes Sen no Rikyu himself and a girl named Komahime, whose collective appearance this Servant is based on.
