do あなた know what ep is tokyo tower bombing,and ayumi's 愛 rival.what i mean によって ayumi 愛 rival is becase a girl fell in 愛 conan and there fighting each other.i think she in 2 ep

The Tokyo Tower bombing is most likely episode 304...
And Ayumi's 愛 rival for Conan is probably episode 126-127. In this episode Ran, Sonoko, and the DB go to watch a classmate's traveling drama group perform. While there, the classmate's (he's in high school like Ran and Sonoko) younger sister, Megumi, starts hugging Conan, making Ayumi very angry.

I hope this helps!!
