Vol 4 Prologue (1/2)

Prologue

I—Mononobe Yuu—have a secret

Three years ago, to protectdestroyed by ”Blue” Hekatonkheir, I drasil

Because the knowledge of power that Yggdrasil trans weaponry from a lost civilization—was too vast in volume, I lost memories every time I downloaded

My younger sister Mitsuki would surely feel sad if she found out about this, hence I kept it secret fro on Mitsuki's face—

But it was already too late

I had even forgotten that Mitsuki was not s towards her had been lost

I am myself Simply this alone would already hurt Mitsuki At soinal self

And it was actually just now that I finally noticed this myself

I confessed this secret, which I had kept hidden into anyone at all

I told the girl who should be theher to shoulder the heavy burden I could not withstand on my own

Inside thetransport shi+p, in front of the cabin assigned toout for help, telling her everything

I struggled internally, trying uilty confession

Iris silently listened to me

”Sorry for telling you this kind of thing out of the blue”

After I finished, I apologized to her with a heavy conscience

—What a?

Stunned at ed in my heart But time could not turn back

”Ho, my mind is totally muddled”

Iris replied to me with a wry smile and wrapped her arms around my back

Full of chagrin, my heart pounded in response

”But if there's one thing I definitely felt, it's that you're relying on me, Mononobe, so don't worry!”

Iris separated from me and looked me in the eye squarely

”This time, it's my turn to help you, Mononobe”

Iris declared with clear determination on her face

There was not the slightest hesitation in her eyes She si at me

”Iris”

”This isn't soo into the cabin to talk I want to hear more from you, Mononobe, to think about what should be done”

Thus, we entered my cabin and sat down side by side on a bed, to continue the conversation

Specifically, she asked me how I lost my memories and why I could not tell others—

Iris asked with an expression of unparalleled seriousness on her face while I answered all her questions honestly

Finally, she stopped asking questions and the cabin returned to silence

I saw Iris silently stare at the ceiling for a while before whispering softly:

”For you, Mononobe, falling in love with me must be the most painful for you”

”No, that's—”

I reflexively tried to deny what she said, but words failed me mid-sentence

Because Iris was right on target What made me feel the worst was that I had betrayed my past self—I had betrayed my promise with Mitsuki
