"Memories of the Ares Days"

Seraph rarely speaks about his childhood.

One day, while the four members of VOLTACTION are organizing old documents, they find a photo of Seraph from when he was a young boy—the time when he was called Ares.

In the photo are a young Ares and another child.

However, Seraph has no memory of that child.

On the back of the photo, written in red ink, are the words:

"The next time we meet, we'll surely be enemies."

Then, a few days later, a person appears before Seraph and calls him by his old name.

"...I finally found you. Ares."

Even though Seraph should have forgotten, the moment he hears that voice, fragments of his childhood memories begin to resurface.
