This character is bonkers. His skillset, that NP (ESPECIALLY that NP -- love the name lol), his "reasons" to be a Summer Servant that makes it feel like he shouldn't ever be summoned outside of this context, period... You did well keeping everything a secret from me on this one! It would have probably gave me more ideas for the design, but at the cost of surprise!

I invite you to make his normal self a ★1/★2 parody Servant much later on, and keep on basing him on that martial artist variant of his. Even he truly should be portrayed seriously, I wonder how his personality as a Summer Servant here would translate in the everyday Chaldea atmosphere.

Gameplay-wise, I think such a demerit-filled kit can be amusing to exploit, especially because these demerits aren't going to kill him. They are annoying for sure, especially the one reducing his NP gauge, but it's not like it would stack defense down or remove his Ruler-type defense. How does his Charm works by the way? Is it a counter? I will need much more time to understand that Noble Phantasm. I'll get back to you when I'm done lol.
