Below that, you say? Let’s see, if I had to give a cold self-assessment… perhaps an emergency shield?”A Solitary Tin Knight, forever barred from human warmth.[The ‘Tin Knight’ urges everyone to initiate the boss battle, saying the cut scene is over!]This is a cruel, fairytale-like adventure story told by twisted protagonists.…Maybe!
