After opening it, an inviting aroma that's a blend of sweetness and bitterness wafts out.
I'll pour it into a glass right away.

The color is a brown that reminds me of the "Golem" from Dragon Quest.
Just looking at the soft color and smelling the aroma calms the mind.

The moment it touched my tongue, I felt sweetness, but by the time I swallowed, it had turned to bitterness.
I can feel the sweetness of the light sugar being swallowed by the rich flavor of the bitterness on my tongue, making for a soothing taste.
You can enjoy a critical hit of richness and aroma by using Sizzle Roasting (roasting beans for a short time at high temperatures).
While being easy to drink with less sugar, it also has a clean aftertaste.

"BOSS QUEST: Tadoritsuita Fukairi" is available for purchase at convenience stores nationwide in Japan and other locations starting Tuesday, September 2, 2025.
The retail price is 140 yen (tax not included) for one can (185g).
