How did Ryoki decide to challenge CITRUS modulation?

A song each member brings memories back.

SOTA
My Way 
by Def Tech
”When I was a student and went to karaoke or had BBQ with my friends, we built up the tension to the maximum with this song.”

SHUNTO

“When I was a high school student, I really liked my friend singing this song too much. I asked him to sing it forever, and we sang together.”

MANATO
奏 Kanade
by スキマスイッチ Sukimaswitch
“I went to school by train. The lyrics start with ‘kaisatsu no mae (in fromt of ticket gate)’. It was easy to imagine the scene and listen to it.”

RYUHEI
Mela!
by 緑黄色社会 Ryokuoushoku Shakai
“I love the vocalist, Haruko-san’s voice which always gives me a supportive push. It's an unforgettableI song, and I listen to it now.” 

JUNON
怪獣の花唄 Kaiju no Hanauta
by Vaundy
“I really enjoyed his music live at Viva La Rock recently. He was so cool, and it was the most exciting.”

LEO
Love Rain
by 久保田 利伸 Toshinobu Kubota
“This is a song I wanted to sing for someone for the first time when I was in 5th or 6th grade. My father and mother used to listen to this at home, and I wanted to sing it for a girl who I liked in those days” 

RYOKI
CITRUS
by Da-iCE
“I sang this at the audition and have memories of practicing everyday. It is a song in a higher key, so we challenge how we can modulate.”

Then Ryota-san requested Harami-chan to play CITRUS with piano accompaniment for Ryoki.

Behind the Scene of B Medley

Harami-chan was worried that she had made this medley a rather difficult arrangement, but she enjoyed it very much. She was amazed at how easily the members managed to pull it off, despite the almost haphazard performance, and said it was truly amazing and gave her goosebumps.

This was the first time for them to lively perform with an instrument.

Souta: I struggled to keep up with the emotional performance even without our own singing.

Shunto: I really had fun. I liked the instruments. I especially felt that way this time.

Leo: A valuable experience. I was surprised when the staff told me about it.
