I Shouldn’t Have Brought a Female Magic Knight to an Ero Trap Dungeon!

The hero has finally arrived at the last dungeon, where the Demon Lord awaits.
However, he’s not confident he can do it alone, so he recruits a party member.
At the tavern, he enlists the services of a magic knight named Tia.
She’s higher level than him, and can use both magic and weapons.
She’s the perfect match for this dungeon.
Or so he thought…
The final dungeon is littered with ero traps, and she can’t help but trip them.
How far will the hero and his new partner advance…?
