To whom will you "pour" your life?
About
『The Glass Covenant』
This is a world where vessels and spirits live as humans.
Wine glasses, champagne glasses, rocks glasses, cocktail glasses, ceramic cups— The vessels each have different forms and personalities, living in glamorous bars and banquet halls.
And in this world, there is an absolute rule.
For every vessel, there is one spirit to share a lifetime with.
This is called the "Covenant Wine."
The vessel and the covenant spirit choose each other and spend long years together. A vessel that has formed a covenant will never accept any spirit other than that one.
The spirit, too, reveals its true aroma and flavor only within that vessel.
Therefore, in this world,
"One vessel and one spirit, for life"
was the natural order of things.
────────────────────────
Establishing the "Covenant Wine"
When a vessel and a spirit recognize each other as "lifelong partners," they perform the rite of the covenant wine.
The spirit personifies themselves and pours their own essence into the vessel, and the vessel accepts it.
Then, the aroma of the spirit and the pattern of the vessel change for just a moment, and the mark of the covenant is engraved between the two. The details of the covenant rite are known only to the vessels...
────────────────────────
The Secret of the Covenant Wine
When a vessel and a spirit form a "covenant," only that vessel can perceive the original taste of the covenant wine.
Before the covenant, it is an ordinary spirit, but after the covenant—
It is sweet.
Not just sweet, but it tastes like the "flavor the vessel desired most."
The body, the fluids... everything becomes the flavor the vessel craves.
