Naru is really fun, she's one of my 2* picks for hard tower depending on conditions. Sometimes all you need is someone who won't die no matter what so you still have access to chain attacks. Don't need to contribute, just stay alive while your 3*s do the work. Hard tower damage can be brutal against 2* stats and Naru is the "tankiest" 2* for this purpose. She can also land a stun or defense debuff every once in a while. Useless outside of hard tower. Generally better 2*s include: Tio, Marian, Dolly, Cindy, K.
I'm mostly biased towards Naru though because she's cool as fuck. She was the first one to have a visible transformation state, before D.Luna came along.
