Tsubaki Yayoi is the best friend of Noel and Makoto, and also a former villain. Tsubaki is very serious and mature, as she previously always followed orders without question. She once bore an extreme hatred towards Noel after discovering that in the original timeline, Noel didn't exist and Tsubaki was together with Jin. After breaking free from her brainwashing, Tsubaki, along with the form she obtained as a villain, "Izayoi", is determined to fight against the villains for what she deems in justice. Tsubaki also is a hopeless romantic, as anything remotely enticing can break her normally calm nature.
