Am I in Attack on Titan with a Death Note???

Zen sat in the corner, his back against the cold wall. Mikasa followed him, standing nearby, her sharp eyes never straying too far from him. Carla was still being treated in the distance, her weak breathing barely audible over the murmurs of the medics.

"..."

"Hmm..."

A voice, low and indifferent, echoed above him.

"So, why did you help them? I thought you wouldn't."

The Shinigami floated just above his head, its skeletal grin never fading.

Zen didn't react immediately. He simply stared ahead, his expression unreadable.

"If you're ignoring me because you're worried others will think you're crazy for talking to thin air," the Shinigami continued, "then let me remind you—you can speak to me through your thoughts."

Zen finally shifted his gaze upward, looking at the death god hovering over him.

'Why do you think I helped them?' he asked instead, his voice ringing in the Shinigami's mind.

The Shinigami's grin widened, its glowing eyes studying him with amusement.

"Is it because… you've never had someone who would stand for you?"

Zen's expression remained cold, but for a brief moment, his fingers curled into a fist before relaxing.

'Probably.'

His thoughts were calm, yet distant.

'I was unlucky in almost everything.'

He exhaled quietly, resting his arm on his knee.

'It wouldn't hurt to stand for some people. I mean… I can do what I can. Though, of course, I have my own benefits in this.'

The Shinigami let out a low chuckle.

"How very human of you," it mused. "Even when you act out of kindness, there's always a cost, always something to gain. But that's what makes this fun."

Zen didn't respond. He glanced toward Carla, who was still being treated, then at Mikasa, who stood nearby, watching him with quiet suspicion.

Zen met Mikasa's gaze briefly before looking away. She didn't say anything, but her sharp eyes told him she was still wary.

The Shinigami, sensing the tension, chuckled. "She doesn't trust you."

Zen didn't need to be told that. It was obvious.

'She shouldn't,' he thought back.

Still, Mikasa didn't leave. Whether it was because she was keeping an eye on him or simply waiting for Carla's condition to stabilize, Zen wasn't sure. Either way, it didn't matter.

His focus shifted back to the Shinigami.

'What about you?' he asked. 'You've been hanging around me this whole time. What do you gain from it?'

The Shinigami grinned wider, if that was even possible. "Entertainment."

Zen just shook his head. "Well, never mind. It doesn't matter. I'll just go with the flow."

'And What will happen to the Armored Titan's powers since I killed him using the Death Note?'

The Shinigami chuckled at Zen's question, floating lazily above him. "Ah, now that's interesting."

Zen narrowed his eyes. 'What do you mean?'

The Shinigami tilted its head, its hollow eyes glowing faintly. "The power of a Titan shifter isn't something that simply disappears. Normally, when a shifter dies, their power seeks a new host—either among their kin or a random Eldian newborn."

Zen frowned. 'But I killed him with the Death Note. Doesn't that break the cycle?'

The Shinigami's grin never wavered. "Who knows? The Death Note doesn't follow the same rules as this world's curses. His death wasn't natural, nor was it one dictated by fate. That kind of disruption… could have consequences."

Zen's fingers curled slightly against his knee. 'So, what? The Armored Titan's power is just… loose?'

The Shinigami let out a low chuckle. "Maybe. Or maybe it's waiting."

Zen didn't like the sound of that. He glanced toward the battlefield in the distance, where Reiner's lifeless body lay. If his Titan abilities had no host…

'Then where will it go?'

The Shinigami's grin stretched wider. "That's the fun part. You'll find out soon enough."
