Arifureta - Episode 09

"Dragon Slayer" (黒竜を穿つ者) is the ninth episode of the Anime adaptation. It aired in Japan on September 9, 2019.

Synopsis
Hajime's quest leads him and his classmates into the mountains, where they come across their quarry--and the huge black dragon attacking him!

Summary
Once in the mountains Hajime uses transmuted drones connected to his jewel eye to search for the adventurers. They find the nobles son, Will, the only survivor who reveals they were attacked by an army of monsters and a black dragon. While returning they are attacked by the dragon.

Hajime succeeds in knocking it from the sky and attempts to pierce its armour with his weapon the Pile Bunker, which can drive Azanthium stakes through any material. The dragon almost escapes until Shea knocks it out with Drucken. Deciding to forgo piercing the armour Hajime sadistically shoves the stake into its only unarmoured area; the anus.

However, the pain causes the dragon to reveal she is a Female Dragonborn, capable of taking a human form and begs him to remove the stake in exchange for everything she knows. She admits she was magically forced by someone to attack Will and his friends and as atonement, offers to help them stop that person. Hajime decides to kill her anyway but Yue convinces him to spare her. He removes the stake and the dragon transforms into a young woman named Tio, a shameless masochist who admits she enjoyed the stake, just a little. Now their ally Tio reveals the person, whoever he is, has an army of 60,000 monsters and is planning to attack the farming village.
