"Ama no Jaku" (Heaven's Weakness), composed by Shiromi (164) for the Vocaloid GUMI, is a seminal J-Pop ballad exploring themes of cowardice in love. Released in 2010, it sparked countless covers, including marasy8's poignant piano arrangement that reimagined the synth-driven original into a contemplative solo piece.
"Ama no Jaku" is a driving, chaotic stage theme from the bullet hell shoot 'em up game Touhou Project: Immaterial and Missing Power (later reworked in Touhou 11: Subterranean Animism). Composed by ZUN, it exemplifies his signature style of blending fast-paced rock and electronica with memorable melodies, perfectly capturing the intense and unpredictable nature of the boss battle it accompanies.
