"Wait, for real?"
"Yes, I'm quite certain. Since your body was already somewhat superhuman from eating Monsters, you've grown significantly more powerful through this Contract than normal humans presumably would. As a result...it may be possible for you to form a second Contract with another Monster. However, another Demon, or a Dragon King or Elder Vampire, might be too powerful to sustain inside of you along with myself," He informed me.
"Well...just because I can form another Contract doesn't mean that I'll get the opportunity to do so. It's incredibly rare, I might even be the only human currently in existence with a genuine Monster Contract, so getting the chance to obtain a second Contract is pretty slim at best," I replied wryly.
