Who is the Cat-Eared Ninja?? Never saw her in the manga...
She's from some old concept sketches by Kui. She hasn't shown up in the manga yet, but I wouldn't be surprised if she shows up some time in the future.
In games like Wizardry, and many of the JRPGs inspired directly by it, the ninja class can't equip any but one or two special armors that only ninjas can equip. (And even then, they're crap-tier and only give 2 or 3 AC and have no magical abilities.) The ninja class instead gets AC by having special evasion and stealth class skills.
Of course, it's presumed that clothes are being worn whenever armor is not, but some people would interpret not having any equipment as "naked"...
Added the Izutsumi tag considering she's now an official character in the manga. Glad to see Kui didn't throw her design away.
You're not wrong but...Oh,by the wayRight?How does that even help!?W-Where the hell did that from?!What?*Wince*I mean, the ninjas you see around town are usually naked.If doing it alone is embarrassing, how about I get naked with you?I mean, It's kinda embarrassing ...Yeah, they're a pretty weird class.I can't seem to muster the courage...Well...I find that hard to believe ...Apparently it makes it easier to move around during combat ...When are you going to get naked?I mean, no... "Ah, there's a ninja."That's not the problem!Yup.
