While people around me cried while watching ‘Demon Slayer’, I am crying alone watching Zico sing ‘Turtle Ship.’
이고 진짜 부채가 일렁이는 파도 같고 지코님이 계신 빨간 무대가 거북선같다

This really looks like waves of debt rippling, and the red stage Zico is standing on feels like the Turtle Ship. But because this is Japan, he looks like a truly patriotic, country-loving super star.
K-Netizens praised him for his bold move at a concert abroad.


- “To do this at ‘A-NATION’ and not a solo concert…”
- “This is what you call hip-hop.”
- “This isn’t some club stage but a huge stage…good!”
- “There’s no reason for him to remove the song from the setlist.”
- “Guys, this is what you call real hip-hop.”
- “Hip-hop is becoming cool again.”
- “Yay!”
- “The colors are of the Korean flag…amazing!”
