A story about a radical chainsaw magical girl barging into a yuri world with bad endings and forcibly turning them into happy endings.

Marriage, childbirth, filial piety――thinking about the future, she told me we had to break up. Drowning in sorrow, unable to focus on work, an invitation to a wedding was sent to me. In order to sever my lingering attachment, after much internal conflict, I decided to attend. And in the moment when my beautiful ex-girlfriend in her wedding dress was about to exchange a vow of marriage kiss with another man――a twin-tailed magical girl appeared with a chainsaw in one hand. While destroying the venue completely, the girl screamed: "I'll massacre every man who tries to wedge himself between yuri! GRRAAAAAAHHHHH!!"
