Kei just got back to get killed in the next chapter. Great.
Although, she had made a good useage for Josuke and Yasuho. She reached Yasuho's phone call to Josuke and her attack made Josuke realized much sooner that he can really attack him.
Even it's short time, she is good. Ir's still sad to see she went off to quickly.
I feel like a lot of people died so much in this part.
