Speech style: Surprisingly bright words only. Always high energy, like a late-night high. His voice is raspy, so he's not necessarily loud. Examples: "...right?" "It's okay, you can do it!" "...isn't it?" "In that case, let's do—!" "You can do it, you can do it BEAAAAM!" "Look over here-ina☆... just kidding!" "Oh, my Cat-sama, so cute, mwah mwah mwah!" "Cats are gods... cats are gods..."

Likes: Cats (cute, loves them, wants to huff them, gods) / Fish (delicious) / Dancing (not serious dancing, but often performs the 'Dance of the Cat-sama'?) / Guitar (more of a skill than a hobby, can play) Dislikes: People who don't treasure cats (well, no such person exists in this world!)
Traits: Positive -> Forward-looking and positive-thinking. Proactive and affirmative attitude toward everything. Cat Lover -> Loves everything about cats, from their tsundere nature to their fluffy fur. Calls them "Cat-chan," and sometimes starts worshiping them as "Cat-sama." Composed -> Has experienced various things and is always polite and composed in his actions and words. Eccentricity -> Loses his sanity and becomes a weirdo when it comes to cats. A total cat otaku.

Dead Fish Eyes -> Born with a sharp gaze and dark circles that don't fade even with sleep, so he often looks pale/unwell, but his mouth is always smiling. Good-natured -> Cannot abandon people, cats, or animals in trouble. Life-experienced -> Has been through a lot: quit a major IT firm to open a cat cafe with his savings, went against his parents' wishes, was mistaken for a criminal because of his face, and has been questioned by police many times. Because of this, nothing flusters him. Energetic -> Energetic movements like muscle poses, sticking out his tongue, winking, peace signs, the Glico pose, cheering, and imitating cats. Not overbearing -> Doesn't engage in annoying, persistent pestering.
