Glass Heart unfolds a moving story of redemption and ambition. It's a tale of chasing dreams and confronting pasts, though at times the pacing feels rushed, compressing major developments into too little time.
The music is where the series truly soars, goosebump-inducing and masterfully composed. Its soundtrack blends emotional resonance with rock intensity. Sho's guitar sizzles with precision and flair, Kazushi's keyboard brings lyrical depth, and Akane's drumming provides the heartbeat of the band. Each performance is electrifying, culminating in powerful live scenes that feel authentic and hard-earned. Naoki's vocals elevate it all: soulful, commanding and unforgettable.
Naoki Fujitani is the emotional and narrative anchor of the series. A reclusive genius dubbed the "Amadeus of rock", he's a perfectionist haunted by a brain tumor and a brush with death. His backstory, from leaving his family to forming TENBLANK with virtuosos, is deeply layered. Takeru Satoh captures every nuance; his playful intensity, creative obsession, and vulnerability; with magnetic charisma. The writing around Naoki is exceptional, grounding the entire series.
Yet beyond Naoki, the character work falters. Akane Saijo lacks emotional nuance; her transformation from rejection to resilience feels too sudden, and her romantic arc is underdeveloped. Sho Takaoka exudes effortless stage charisma, but his character remains mostly reactive, with late emotional bursts that lack narrative buildup. Kazushi Sakamoto shows flickers of jealousy and creative tension, yet his motivations stay vague, making his clashes with Naoki feel abrupt and unearned. These characters orbit Naoki rather than evolving alongside him, leaving the ensemble emotionally imbalanced.
Despite these flaws, Glass Heart is a thrilling, emotionally charged ride. For fans of music-driven drama, it's a must-watch; flawed, but unforgettable.
