Tamaki transferred from the 1st Fire Brigade to the 8th, where she now works as both a firefighter and a nun—though her role as the latter seems mostly ceremonial, given her habit and the oversized bunker jacket she wears like a dress over black tights. Her third generation ability, which she calls "Nekomata," transforms her into something distinctly feline when activated. We're talking forked tails, cat ears, and claws—the full package.
What she's probably best known for, though, is her comical clumsiness. Tamaki frames it as her "Lucky Lecher Lure," which is her way of saying that embarrassing situations seem magnetically drawn to her. Rather than owning these mishaps, she tends to blame whoever happens to be nearby, which fans often find endearing in its own absurd way.
