This is a very good debut. I hope they manage to put out equally strong songs in the future. I'm hooked. And for the producers: Try to keep up the illusion of an endless white room by avoiding to show the ceiling structures in this kind of videos... This makes it look way more professional...
0:15 I really like her rapping flow and tone (reminded me a lot of Genglue's XXIN) and she also had the cutest outfit. 0:29 my favorite vocal part overall, and my cutie bias Aguri-chan. 0:43 Wow she's got a strong voice 1:39 Another really strong voice. This group is very strong vocally. 2:00 Aguri-chan's part here is good but I feel like this part itself is forcing her to be subdued in her delivery and we're not seeing her full singing ability yet. I look forward to seeing more of this group.
