Infinite Reload

Tenka frowned: "What are you trying to do?"

Yachiho didn't answer her but walked toward Kyouka: "You failed to protect Himari."

The Chief of the 7th Unit used her sword as a cane to stand up: "I know. It's my fault."

"Then help me save her. Lend me your slave."

Yuuki Wakura walked over: "What do you need me to do?"

"There is an idea I want to test."

Yachiho grabbed onto the chain around his neck, which caused Yuuki to take on a different form.

This time, he transformed into a tall, heavily muscular humanoid with golden armor plates.

Yuuki closed his eyes, then said: "This form is called Slave: The World. Look like it can manipulate time, but only for 2 seconds."

"Good, that's all I need."

Yachiho jumped onto his back: "Since I acquired Golden Hour, I have been thinking about how to overcome its drawback and limit. One of these ideas is to cooperate with another one who also has a time-rewinding ability. I'll use my Golden Hour to rewind time for 5 seconds, then the other will use her ability to reset me back, so I can use Golden Hour again to reset her, and continue like that. Theoretically, it'll allow us to turn back time by an unlimited amount. I call this technique Infinite Reload."

"That sounds like a power that humans shouldn't possess."

"Maybe, but I'm willing to try anything in order to save Himari. Ready, Slave-kun?"

"Ready."

They shouted, in unison: "Golder Hour\The World, bring time back! WRYYYYYYYYYY!!"

When Yachiho regained her senses, Yuuki has already transformed back to his human form.

"Did we succeed?"

However, when she looked around, the landscape was completely different. There was no sign of the battlefield. No crater, no crack, no footstep. Even the dorm of the 7th unit wasn't there.

Yuuki reluctantly said: "I think... we go back in time much farther than we intended."

"But... I feel like I just activate my Golden Hour..."

"I feel that too. Maybe it's because when we use Infinite Reload, it also resets our memories. If we aren't interrupted by the end of my transformation, we may continue to rewind time forever."

Yachiho let out a breath of relief: "I never thought of that problem. Guess that we're lucky this time. Anyway, let's go save Himari!"

Yuuki:"... Did you forget something?"

"What do you mean?"
