Tập 4: Rokka tập luyện cùng Raise A Suilen và nhận biệt danh LOCK

4

With Rokka becoming the temporary guitarist of Raise A Suilen, the band heads to a film studio to shoot a music video of their new song. Afterwards, they return to the studio to play said song, but Rokka struggles to play together with the other band members. After a chat with Masuki in a ramen shop, Rokka keeps practicing until the song is perfected. The next day, the band is impressed by the video they put together, and Chiyu removes the interim label from Rokka's title, giving her the nickname LOCK. (Source: Wikipedia)
