For Kira, it is almost a Tradition to devour her enemy if possible (or at least one of them when against a group), reassuring them of her rather merciless power even after battle and regardless of her state of hunger. She would even overeat herself sometimes but the bellyache she gets out of it is worth it in her eyes. She just loves to run her thick, fleshy tongue along her prey, letting their heads rest on it as they stare down her throat and get sent down slowly. On rare occasions, she even devours something too big for her belly, causing it to bulge a bit, even when its completely empty. In those cases, she sadly is grounded from flight and has to wait until all that weight inside her has been decreased
Oh and funfact, her love for living prey spawned during her late teenage years. I already have a short comic planned so prepare for that one~
