A friend of mine has been reccomending me to read berserk for 3 years now (since our college started) . But back then my siblings were like- you're not reading it till you're 18. Well Im 19 now already but my siblings still don't want me reading it. But I'll soon graduate college and my friend is still persistently reccomending it to me.

Is it that bad or are they being over protective?
