After gaining two new succubus allies, Naoki's party sets sail for the Kingdom of Aldam. But it isn't long into their journey when they discover that the ship they boarded is owned by none other than the Princess-turned-adventurer Marie herself! However, instead of dragging the Hero back to Lesbule Castle, she proposes a different solution -- a sex battle between the girls and the knights of the royal guard to determine once and for all who is worthy to journey with Naoki to defeat the Dark Lord!
It's more sex and mayhem on the high seas in this sixth installment in the Tales of a Harem in Another World series!
