This volume hits hard right off the bat. It must have been the shock of a lifetime when Goku rocked up to the small get-together after 5 years with a child that he claims is his own. I'd be kind of worried, since he's not the most reliable character, and I'm not sure I'd trust him to raise a child. And then a violent party crasher arrives to spoil everything. So yeah, this volume goes kind of hard.
