Idk about other but though tokyo revengers are good yet it just gives a bad impression about Japan and it's students to in other countries...... Maybe such things don't really happen but japan's students will be seen and judged through this anime/manga. I know it's just a anime but if any student mainly high schooler will see it, it will just provoke them to fight and kill....... I like anime but something like this will just end up bringing voilence in children.
If you talk just about story it's 8/10.....because some things are yet to be explained and I haven't completed it yet so I can't give it a 10
