I'm the Hero, but the Demon Lord's also me volume 3 - Tatsuya Endo and Akiyoshi Ota

 Aw right, it's time for the third volume of this hilarious isekai harem series, with a serious ecchi touch.

Because oppai to the left, oppai to the right, oppai everywhere in this series.

It seems that both the followers of the demon lord, as the followers of the hero, prefer to spend their days topless.

A sacred dragon appears, to warn Yuuma that the demon dragon clan Berserker princess is coming to Earth to challenge him.  In order to defeat her, he must also find the demon sword, having only access to the sacred sword at the moment, hidden in his best friend's bossom.

But Carina ended up lost in our world, and takes on a kindergarten teacher job to pay for her eating bills, as she didn't know her gold coins weren't a method of payment.  When she finally gets on track of the hero, Yuuma's father, the former hero, faces off against her.  He does this to draw time for his son to arrive and get the sacred sword out of his friend to battle Carina.  But he is no match, until one of his classmates appears and turns out not to hold, but actually IS the Demon Sword.

Well, another good laugh for sure, and now it is only the final tome that needs to be read, sadly concluding then this fun little series.
