Young, naive and playful.
Older Daiku: Playful, less naive, optimistic
Clothes on the pic, that's it!
Inu...ish, it's the best definition he can give you from what he knows what he is. Maybe he'll tell you more. There's one certain story he really likes and wherever he goes more episodes arise.
Death's Dog, Inuyasha, Cerberus' Arch-Nemesis:
The story started small, chicken being eaten, cows being shred to pieces. But after a short while Daiku began to hear stories about this bulky animal in which people got murdered, slaughtered to still the beast's rage. Daiku doesn't know why he likes this story, he just remembers them. There are certain skills that this beast has. Apart from a tough body and unbreakable claws, fast recovering wounds and an unstoppable rage.
Hunger- Death's Dog has got a huge hunger for power, like all demons. From every enemy that hit kills he takes the soul and eates it, fuelling its own power. The amount of power he gains is determined by the power of its victim.
Rage- Death's Dog is just as much addicted to blood as it's addicted to power, but the strength it gains from blood is just temporary. The sight of blood is enough for it to empower it, but the taste is so much better. Its sight will become slightly worse, but its adrenaline will allow it to move much faster than anyone else. More blood, more power, how longer the taste/sight of blood is there, how longer the power stays.
Pain- Death's Dog isn't immune to pain, not at all. But pain can't stop it, it's just a stimulater for it. It'll increase its rage and hunger, its strength and prowess.
These are just a couple of its skills, every now and then Daiku hears about a new one, and he remembers it. This is the only bad/scary/saddening story he knows.
