The 'Star' seems to be the defining motif for both Julia and Kasumi. Julia has a blue star on her left cheek. Her song 'Ryuuseigun' means 'meteor shower' or 'shooting stars' (coincidentally, 'kirakira' and 'dokidoki' appear in the lyrics). Both their signatures incorporate stars.

Moca (September 3)

Wonder why Moca always sounds so sleepy? Because she was born on Good Sleep Day, also known as Bed Day (ベッドの日)! 9/3 sounds like 'good sleep' or 'gussuri' (fast asleep).

Tae (December 4) 🎂

She came to this planet on ET Day (ETの日). O-Tae is alien confirmed.

Kasumi (July 14)

Her birthday is also Sunflower Day (ひまわりの日). Yumemiru Sunflower!

Rinko (October 17)

The birthday of this avid gamer falls on Japan's Online Game Day (オンラインゲームの日). Of course.

As Roselia's「FIRE BIRD」has just been released this week, I was delighted to know of a Betadori reference they snuck into the lyrics. The spoken line「羽撃こう…頂点の夢へと」, meaning 'Flap your wings, towards our dreams at the top".

RAISE A SUILEN might be a homage to RAZES/Betadori. Try reading the band names one after the other. In「EXPOSE 'Burn out!!!'」, you have the line "Get your gun! Let's shoot! Bang! Bang!"

In「A DECLARATION OF ×××」, the line "In the name of us" harks back to the mission of RAZES.
