What kind of absolute nonsense was this. Despite exhaustion tugging at his every limb and the very much still present soreness in his wounded chest, Aurum had made it a special responsibility of his to keep watch over Arrow's house that night, along with several others. With all of this stealing nonsense, Aurum wasn't particularly in a mood to just leave her unguarded and all alone, even if Arrow was the type to insist that she could keep her own shit safe. So, when Kaito finally came along and landed on Arrow's roof, the proxy was nearby, nearly asleep with how much his body was begging him to rest. His head whipped upwards when he heard the feline's call, and his eyes immediately narrowed in anger, a snarl leaving him. Spreading out his wings, Aurum ignored the prevalent exhaustion and ache as he took off,  flying up into the sky. He landed delicately onto the roof nearby, his one good eye ablaze as he faced Kaito down. The male seemed vaguely familiar in the back of Aurum's mind, even with all of the accessories, but he couldn't exactly put it entirely together, too focused on the task at hand. Tail lashing and twitching behind him, the lion rumbled lowly, his voice an intimidating and deep timbre as he spoke, "You... you're the one who left that note for Arrow, didn't you? I don't know who the hell you think you are, but you can very much fuck off now." Without giving any sort of warning, Aurum launched himself forward across the roof, attempting to barrel into Kaito and dig his claws into the other's sides. He would attempt to pin the other down, hoping to capture him so that he could be unmasked and judged accordingly. He wasn't going to risk using his fire elementals on the guy, both to spare Arrow's poor roof, as well as so that he wouldn't just end up killing him while attempting a capture. If this mysterious weirdo ended up being from some other group, that meant that Tanglewood could go to them and tell them that one of their members had been fucking with other groups and stealing things. And if it was someone from within Tanglewood? Well, ultimately it would be up to Leroy to decide, but one of the ultimate things Leroy was coming down on was not harming clanmates, and stealing shit from others was pretty damn harmful, even if it wasn't a real attack.

( sjfjdjg Kaito can dodge, obviously )

Truth be told, Aurum had not been attempting to inflict physical damage upon Kaito at all. He knew how to keep his claws back enough that they were fit more for grabbing than for mauling, and he really had been just trying to grab the kid so that they could figure out what the fuck was going on. However, Kaito was quick, and Aurum was very tired from not only forcing himself to stay awake through his injuries, but also forcing himself to stay awake for this whole little ordeal. So, when Kaito slipped back his claws and jaws, Aurum couldn't say that he was overwhelmingly surprised. Thankfully, the proxy managed to get his paws back underneath him before he slammed into the roof, knowing that if he had fallen down onto his chest, he would've been in a great deal of pain. The lion found himself whirling around just in time to watch Kaito leaping into the house, a soft snarl of aggravation leaving him. He called down to Miller, something akin to but just less than a scowl on his face at the other's earlier comment, "I was just trying to grab him! We need to make sure he doesn't get away!" He figured that much was obvious, but he also knew that Miller was a man who thrived on commands, and since Aurum was the highest ranking guard around Arrow's house, he took it upon himself to dole those orders and explanations out, even if it didn't come very naturally to him.

Tail twitching behind him, Aurum slowly descended down to the roof tile that Kaito had knocked out of place, taking special care as Roy had instructed him. He didn't even really want his kid around here right now, since God knows what Kaito was planning on doing – even if he didn't seem to be that violent – but he knew trying to send him away would be essentially a lost cause. Taking a deep breath, the lion crouched at the edge of the roof tile, calling down inside, "Kaitou Kid! This is not going to work out well for you! If you just come out of the building and surrender yourself, then maybe we can give you some leniency!" Since outright violence hadn't worked, Aurum stayed perched at the very edge of the new hole in the ceiling, trying to watch Kaito and see where he was going. Picking his head up for a moment, Aurum rumbled at Miller down below, "I want you and somebody else at the front and back of the building. If we can trap him in there, we can catch him." It was a simple enough plan, but would hopefully be an effective one. After all, if Kaito didn't have any way of getting out of Arrow's house, he would be forced to remain trapped inside of it, or surrender himself and whatever loot he had acquired. Besides, if Miller had a better idea, then Aurum was sure that the other would speak up and offer his advice as well.

Tanglewood's laws were few in number, and as far as he could recall, there weren't any which explicitly barred petty thievery. However, the lack of severity did not bequeath any Butch Cassidy wannabes the right to break into another Tangler's with the intention of bagging some goods. Such is an insolent violation of one's privacy, and that wasn't something the general would stand for. In his tribe, he wanted everyone to share a solid sense of security, and Kaitou Kid's actions went against that.

The wolfhound's arrival came rather late, and as a result, he misses the initial attack on the burglar. Hell, he didn't even catch a glimpse of the meek little fuck; all he understood was that a housebreaker occupied Arrow's home, Aurum stood atop the roof like a nincompoop, and Roy and Miller hollered from the ground level. Where Arrow was currently located, he didn't know. Half of him hopes that she's far away from what could be a possible threat, though at the same time, half of him wishes she were inside to beat the intruder's skull in. He'd make sure to follow up on that last part on the occasion of her being unavailable to, if need be.

"Get the hell outta there, ya sonova bitch!" he bellows, coming to a halt next to Miller. "Do what the scary lion says, or you're gonna get in shit." If the runt had any brainpower upstairs, he'd take heed and get the hell out. Because honestly, thieves really pissed him the fuck off.
