Hope, if he can get evil pieces, they could will modify them so there is no slave part in it or race change. Just power boost and some sort of distance communication (like when one is in danger to notify others). Also why have pawn pieces and instead only use one king and turn all 15 others in queen piece... maybe custom mutated to fit based on the individu al it is intended for. Heck, while at it, why not create his own version in combination with servant cards (archer, caster, saber... etc) , maybe base it on tarot cards, in 'Lord of Mysterys' style (fool, world ... etc).
This chapter is oddly heartbreaking. And I mean Vene and Zei's relationship. The romantic love fading between them and the way they tried many sexual things and play around until they got bored of each other and drift apart. I think this is a part of long lived or immortality that I haven't considered. Does love simply end like that? I would understand if there was conflict but to just drift apart like that is scary to me. What about MC and his harem? They were all love loved so is it like Meridian said? A moment of happiness in their long live of my existence? A billionaire years? Will that be how long it takes? I think I prefer being mortal and dying with the love rather than living long enough to see it whether out. That's oddly sad in the most heartbreaking way possible.
