At Stand Umineko SiB100, a beer pub at 2-16-2 Dogenzaka in Shibuya, a new guest beer from Derailleur Brew Works was introduced. The beer is titled '儿ナティッ勹☆ヴァィフ〃ス↑↑ゃレよ″+ニレニぇω ファィャーマジ卍'. Its style is listed as Luminous Black Light Ale, with 4.0% ABV, 21 IBU, and 9 SRM, so the concept is playful while the drinking profile stays light.

The recipe centers on malt, lemon juice, hops, and cardamom, with vitamin B2 used as a coloring agent. The hops are East Kent Golding and Target, and the yeast is Lallemand - Windsor. The brewery's description points to a body with a touch of sweetness, layered with cardamom aromatics and a lemony acidity that gives the beer a cola-like impression. It should read as a crisp, easygoing pint rather than a heavy seasonal one.

The standout feature is its reaction under black light, where it glows yellow-green. That visual hook makes it memorable beyond flavor alone. For drinkers looking for a characterful guest beer in Shibuya, Stand Umineko SiB100 offers a setting that suits this kind of experimental, conversation-starting pour.
