There's more to Hachi & Gin than what meets the eye.
At first glance, you'll notice that they possess the distinct characteristics of canine demi-humans. At second glance, you'll be surprised to find that they dress in well-pressed high-end suits and slick back their hair with gel. By the third glance, you'll discover that they carry a deadly shotgun and rifle... If you stick around for a fourth glance, you might even notice that one of them is always holding a mint lollipop! And if you make it to the fifth glance, you'll learn to appreciate the humorous banter, which seems to amuse everyone they meet.
Are these two strange people really the most famous art dealers in Umbraton? I'm kind of looking forward to seeing them next time to discover something new.

Are you curious about our story? Hang on... You don't think that Gin is actually my brother, do you? No, not at all... We don't look alike at all! Even different species, for heaven's sake! Some people have even mistaken him for an Eclipsite!
Although Gin and I are not brothers, one might say that we are closer than that. We go back—way back... Since before I can remember, it was just my father and me through thick and thin. My father shut himself away from the world in a small dark room, painting all day long, and was often distressed by the creations he produced. I didn't know how to comfort him, so all I could do was try not to disturb him. During the day, I ran around the yard, and at night, and slept next to my weary father. In fact, I wanted for nothing, but I had no one to play with. Fortunately, Gin soon came into my life, and things became much more interesting.

%s, don't listen to Hachi. As you can see, I look nothing like an Eclipsite. I should tell my own story, so %s won't be led astray.
When I was a child, I lived with my parents, of course, but to be honest, those memories have become very blurred. I remember when I was about eight years old, Umbraton was attacked by a swarm of Eclipsites. An Eclipsite injured my parents, and there was nothing anyone could do for them. I ran away in desperation and finally fell at the doorstep of a nearby house. Just as my eyes were about to close, a painter stepped out of the house and carried me inside. Later, I heard that Hachi had sniffed out my scent and asked his father to come out and save me.
Then the painter adopted me. Actually, Hachi was adopted too, you know, so we both became his adopted sons. But the problem is, Hachi thought that the painter was his biological father. It was not until we grew up that he learned the truth from the painter. The expression on his face at that time... was a sight to remember.

I was glad my father took in Gin—I finally had a playmate! Though, it was a pity that Gin was always so gloomy back then. His face was sallow and melancholy all day long, as if someone owed him money. But I didn't care. Under a bombardment of constant affection, Gin finally became willing to speak to me!
After Gin came to live with us, father started to spend more time with us both. Gin was interested in nothing but paintbrushes, so father began to teach him how to paint, slowly but surely. Ah... I was just flipping through those painting albums. I have to say, some of the comments were quite biting. After teaching Gin how to paint, my father would come and tell me how to appreciate art... At that time, father's paintings were not selling well. Sometimes, the three of us were unsure of whether our next meal would be our last... But looking back, I was very happy back then...
I will never forget father and that painting... I must make enough money to buy an airship! I must fulfill his dream...

Pay no attention to Hachi. Sure, he has a big mouth, but he can be sensitive as well. Our father's death took a heavy toll on him... Yes, our adoptive father died when we were fifteen. Thankfully, he died a peaceful death.
Hachi and I had no choice but to leave the house and find a way to make a living for ourselves. Somehow, Istvan took an interest in us in a short time and gave us the opportunity of a lifetime. But Hachi and I were so used to enjoying our freedom since childhood. We preferred the freedom to work alone rather than being constrained by an organization, so we refused Istvan's invitation. Luckily, Istvan was not angered by our choice. He still provided us with job opportunities and the promise of long-term cooperation, allowing us to participate in his gang's mercenary training for free. So we were ultimately willing to work for this trustworthy new partner of ours.
We are one of the best painting duos in Umbraton now, and as far as Hachi is concerned, we are the best painting duo in Astra!
Our adoptive father left us an oil painting that depicts the entire continent of Astra from the sky. That's why Hachi wants to buy an airship. It is his dream to look down at Astra from on high, and mine too.
