do anda know what ep is tokyo tower bombing,and ayumi's cinta rival.what i mean oleh ayumi cinta rival is becase a girl fell in cinta conan and there fighting each other.i think she in 2 ep

The Tokyo Tower bombing is most likely episode 304...
And Ayumi's cinta 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!!
