And he do his vengeance with a smile and get that maou to combo with him.. A path of vengeance while laughing... I was forgetting the title too, but i dig every title and synopsis on The list... Took me weeks!
yeah...Nidome no Yuusha..i love it..especially when he torture that Princess!!! He should have stole the princess chastity(i'm just saying)
And? How was the story? Although it's somewhat slow, I think you should be able to read some chapters.
