Luminescent

Investigation

Lightning burst into the room unexpectedly when Rin, Mephisto, Amaimon, and Bon were in the bath together.

Rin had smelled him a kilometer away and he was sure Mephisto and Amaimon had too. Hell, Bon could probably smell that man at least half a kilometer away. So, Rin was ready to catch the man's hand when he went to grab Mephisto by the face to pull him out of the water. The Time Lord berated Belial for letting the man pass him.

Lightning pulled his hand back and showed them a picture on his phone. "This seal showed up on the nape of a man who died this morning after I interrogated him. He was bound by a Morinas contract and killed by "Death" when he spilled the beans. Death is a messenger of Time, so you either ordered it as your familiar or made the contract yourself." He accused, still smiling like he hadn't just accused the Demon King of Space and Time of murder.

Rin remembered where he'd seen that symbol as soon as he saw it and Lightning carried a familiar scent that he only just now noticed under all the filth.

"You killed Gramps?!" He stood abruptly, grabbing the Investigator by the throat. "Why were you in my old home?" He demanded, his blue eyes going demonic in a second, irises glowing electric-blue and pupils slimming to slits "This is exactly why I left." Suguro muttered, sinking down further in the water. "Woulda been sworn to secrecy and I didn't wanna know things that could hurt you."

"I'm doing an investigation on the Blue Night–your rumored birth. Know anything worth my time?" Lightning turned his questions to Rin. "I know that my birth isn't something anyone should look into. Sometimes, you gotta know when to let secrets stay secret. For some reason, humans never seem to understand that even after being told so." Rin growled, fed up with people treating him like a puzzle to be solved.oghtbing was slooking at him now like every exirvist looked at him as they passed–like Rin himself was a secret to be revealed. A gentle hand grasping his wrist encouraged him to let go of Lightning's throat. He let go, but there was no mistaking the hostility in his glare. Those eyes had a glow in them that gave even Lightning chills. Dig up my past against my wishes and I'll bury you with it.

"Ah Dearest, you're learning how to play the games you need for war. That's good." Mephisto pulled the boy to him with an approving grin and Rin relaxed some, though his piercing gaze on the Torturer didn't let up until  Mephisto tilted his head to look at him.

The two seemed to have a silent conversation between them and Lightning sighed. This interrogation wasn't going how he'd planned it. Of course, he hadn't planned for his ex-apprentice, the son of Satan, the Director of the Japan Branch, and the Demon King of Earth to all be in a bath together and totally comfortable with each other either. He briefly wondered how Suguro had gotten involved with them, but quickly deduced that was probably Rin's doing.

"Who are you loyal to?" Rin demanded, finally turning back to him. Lightning raised a brow under his shaggy hair. "Why does it matter?" He countered. Before Rin could snap at him again(Lightning could tell he was going to because the teen's tail was lashing the water like an angry whip with a mind if its own), he held his hands up in surrender. "I just like Demons. I like studying them. I like knowing the truth. Whoever lets me do that, I'm fine working for them." He answered honestly. Rin considered the response.

"Hm. I see. Well, you won't get any information out of any of us today, so scram." Rin told him. Lightning wondered what was going on in the boy's head. He'd really let Lightning go, just like that? Even after it was clear the man wouldn't stop until he knew the truth? Rin Okumura was interesting. He played with demons, but his heart was very human, it seemed. Lightning took his leave.

"Should we stop him?" Rin wondered quietly to Mephisto when the doors closed. The demon shook his head. "No, Dearest. I'll send him some much needed clues and then we'll follow him in his endeavors. I shall explain on the way there." The demon answered.
