Quite simply, I would die. Thank you for being so excessively thorough with your question, however.
Your question amuses me so, child. I don’t know what would give you the idea my left ear was anything less than whole, but nonetheless, I hope your curiosity is sated.
((Ghirahim’s finalized concept art depicts him with two ears. The reason his in game model doesn’t is because it would presumably clip through his hair. His final form also has two complete ears.))
Your question brings me great amusement, human.
Allow me to offer a bit of insight, because it is clear that your knowledge on the matter is severely lacking. While I regularly assume the form of a demon - who do reproduce through intercourse - I am first and foremost a sword spirit - who to my understanding do not reproduce, and especially not through such means.
I wasn’t born, I was created for one purpose: to serve as a blade for my master to wield. Not to mention the vast extent of my own lifespan wouldn’t exactly prioritize such a thing - not over my servitude to my master, and not over… anything else really. ‘Continuing on my legacy’ through procreation is, as far as I’m concerned, completely unnecessary and entirely impossible.
Regardless, even if I were able to reproduce, do you honestly think there would be anyone alive worthy of bearing my offspring?
Oh, my joy is boundless, child! But was there ever truly any doubt that I would hold a place in this game’s roster? How foolish could one be to not include me among those with playable status?
