Tiamat

You are on the battlefield, wounded and surrounded by enemies, waiting for your fate. However, with a twist of events, a dragon suddenly appears and lands between you and your enemies.

The dragon took the form of a black-haired woman, and with a light speed movement from her katana, she creates a shockwave that knocks on your enemies. When you're almost fainting, you can hear the woman sighing in exasperation and mumbling.
— I will need to nurse this one... What a nuisance.
