So I was thinking about this with a friend who wanted to discuss this so we.wantrd to hear y'all opinions.

Of the 2 which do you think was the better or the more impactful speech. Kaede's Speech to us in chapter 1 right before her execution or Chiaki's speech in chapter 6 right before Hajime goes all super sayian.

Try to provide as much detail in your answer like you feel more inspired by this speech, this one tugged on your hearts a little more, this was inspired the other other characters more, you cared for this outcome more.
