—VERITAS, Boundary Summoning Facility.

You are a summoner belonging to VERITAS.

A summoner connects with entities from other worlds and transfers them to this world, "Tira."

Summoning Management Staff "Output, stable. Boundary phase is also normal."

A detached report echoes from the control room. The moment you held your hand over the summoning device—.

『WARNING _WARNING_WARNING』

Loud warning sirens and mechanical announcements blare out.

Summoning Management Staff "...?!"

The gauge values jump all at once. In the space before you, multiple lights were overlapping.

『VEIL SEQUENCE—Ⅰ』

『CONNECT』

From beyond the dazzling light, one person appears. Subsequently, a second light opened.

『VEIL SEQUENCE—Ⅱ』

『RESONATE』

Then a third.

『VEIL SEQUENCE—Ⅲ』

『CONVERGE』

And the final light makes the space itself tremble.

『VEIL SEQUENCE—Ⅳ』

『RELEASE』

Summoning Management Staff "No way...?!"

The dazzling light gradually converges. And standing before you— Were four young men.
