At Cafe Utako, Mayu and Katrinna Mae were preparing some dishes for BTS. While fixing the tables, Mayu gets a call from Yukinari. She answers the phone and asks, "Yes Yukinari. What's going on?"

"Mayu, I think we have a problem," Yukinari says, "BTS, they just arrived here in Japan. I found out the Dark Musicians devised a plan to use them to hurt Princess Hoshiko. They're on their way to your cafe right now, so tell the others."

"Right," Mayu says hanging up, "Katrinna Mae! We have a problem!" Katrinna Mae comes into the dining room, where Mayu and the others were, and asks, "What is it?"

Mayu says, "Yukinari called. He said that BTS is in danger." "How?" Hoshiko asks. "He says that the Dark Musicians are trying to use them to take your powers Hoshiko," explained Mayu, "and that we need to help them. They'll be here after settling into your aunt's house."

"We got to help them!" Hoshiko says. Everyone nods, and rush out of Cafe Utako. BTS was already on their way to the cafe.

Jin was looking at the online menu on his phone and says, "I can't wait to try their curry balls and soba noodle salad." "Calm down, Pig Hyung," Jimin says to Jin, "you'll be able to eat all that when we get to this Cafe Utako place."

Jungkook says, "I hope they have good food there. I've always wondered what it's like eating at a Japanese restaurant in Japan itself." "Today will be your lucky day then," V says, throwing his arm over Jungkook's shoulder.

Wakana and Takeshi were spying on their targets. Takeshi nods, and Wakana yells, "DEMON'S FIRE NET!" making a net made out of black flames trap the boys.

"What is this?!" Jungkook says. Trying to break it, J-Hope says, "I don't know, but it looks like a net made out of flames." "That's correct BTS," Wakana says.

Still trapped in the net, Jimin says, "Hey you! Are you that Dark Musician chick that tries to fight the Music Guardians, including Princess Hoshiko?!"

"Correct, you seem familiar with us," Wakana says, "and I assume you're Park Jimin, the insure one of the bunch, short, has a baby face and a well toned pack of abs. You're more cuter than I thought."

"But it's too bad that me and my sister have to use you guys so we can capture the princess and take her powers," Takeshi tells them. Takeshi was about to do it when the Masked Guardian came in.

He threw a lightening bolt and yelled, "LIGHTENING SMASH!" making it hit the net. Afterwards, the Masked Guardian yelled, "THUNDER CRASH!" which made this lighting bolt explode, freeing BTS.

"That's as far as you go, Dark Musicians!" Hoshiko exclaims, "By the power of music! For the love of Harmony and peace on Earth! I'll make sure you seek justice!" "The only thing were seeking is BTS's energy so we can get your forbidden powers Princess Hoshiko!" Wakana exclaims.

She takes her clarinet and yells, "DEMON HELL FIRE DANCE!" making her flames go towards the Music Guardians. Akemi gets in front of everyone and yells, "SAKURA DRAGON CELEBRATION!" and spins around, making a dome protect herself and everyone else.

Takeshi places his hand over Jungkook's mouth, and forms a sharp icicle in his hand. He then attempts to hurt the maknae of BTS. "Leave that young man alone!" Katrinna Mae exclaims, worried about Jungkook, "BEAR BEAST GOD ASSAULT!" making her bear get Takeshi off of Jungkook.

Suzume yells, "LION'S ROARING MAGMA RUSH!" which caused magma to rise from the ground to trap Takeshi's feet. Hoshiko finishes him off, yelling, "ANGEL'S HALO TRAP!"

After being trapped and zapped by the halo, Takeshi falls to the ground. Wakana puts her older brother on her shoulder, saying, "We'll get those pretty boy Koreans' energy and defeat you Princess Hoshiko! Just you wait! We'll make sure you join your father!" Her and Takeshi left for the Dark Music Kingdom.
