Since Deus had confirmed from his system that his girlfriend was indeed an alien or from a sentient humanoid race from another planet, would that fall under joining the side of the aliens and betraying humanity?
Deus was confused about that since such a thing had yet to happen, mainly because humanity has yet to meet a sentient alien in humanoid form with human characteristics.
Of course, Deus was well aware that some sentient humanoid aliens had already managed to infiltrate human society.
An example of such an alien was the pink-haired girl that Deus had met before who was his first customer when he had sold lemonade. The main reason why he had thought of her as an alien was because of the currency she had used to pay him which was Zenchi.
And because of that alien girl, Deus had enough Zenchi to purchase the secret offered to him by Tycoon. So it was no wonder that Deus didn't forget about that alien girl aside from her noticeable and unique pink hair.
