Another one of those funny two-mode dolls. She's actually not an awful damage dealer, but her damage is still less than other dolls that are pure damage dealers. Also, despite having a rifle mode, she can't equip AP rounds so you're stuck with only the AP stats you get from her skill.

She might have use in some formations (mostly shenanigans), but most people probably won't use her.

The meme potential of a girl with a camera and a smiling face is good enough reason to have her (now that we have multiple secretaries), but she's also not half bad as a combat unit. She gets a shield, and having the shield gives her FP buffs, while losing the shield means she's getting EVA buffs. The uptime is quite good, so she's not a bad side DPS (she has a 69% damage buff at 2 stacks and 119.7% at three stacks) that can sub-in for off-tanking and can even work as a main tank (44% eva at two stacks and 72.8% at 3). The problem is the optimal timing can be a little iffy, but she's alright for AFK fighting since it'll generally be good enough, just not fully optimized. The tradeoff between her and SR-3MP is just uptime vs power.

As expected of the main girl I guess.

Oh, and her tiles are weirdly shaped, but this is not uncommon for off-tank dolls anyway.
