Assassination Classroom Season 2 Episode 4 English Dubbed Episode Title:Spinning Time.Episode Description:Itona creates a prototype of a remote-controlled tank, which he plans to strike at Koro-sensei's heart as being the weak point. The other boys in the class suggest a fisheye lens and a camouflage design for the tank, but it later gets destroyed by a weasel. The girls soon figure out that the boys potentially wanted to use the tank to spy on them. Later, Masayoshi (Justice) Kimura feels embarrassment over his written name, Justice. The students are assigned code names by Koro-sensei during a training session against Karasuma, leaving Kimura assigned with his true name to show how well it fits him. Kimura is inspired by Koro-sensei to accept his true name, not by how it is written, but by how one is associated by it.
