Quoted By:
Source, 15 yr fan of Hello Project (Morning Musume), and AKB48 and related groups.
From a standpoint of the original vision of Cover, and Yagoo's original dream of creating virtual AKB48 style idols, who need to be:
-hardworking: never give up, always look to improve
-connecting with audience: being there and present for the fans, through zatsudan, sharing personal experiences, etc.
-singing: singing "well" is good but more importantly, singing with passion and from the heart
-dancing: same as above, you don't have to be a prima ballerina but you need to have passion
-girl next door: this is not a stacy, most popular girl in school. AKB48 style idols should be a girl you feel would be a neighbor, childhood friend, or quiet girl at school
-respect for idol culture: what it stands for, knowing it's history, knowing who's who in the idol-sphere
-passion for idol culture: wanting to be a part of it all, improve on all idol qualities
-seiso-ness: this doesn't have to be all or nothing. Long gone are the days of publicly shaving your head in shame. You can be quite un-seiso on the surface, in fact it makes you more endearing, but you can't have deep yabs like public BF's, collabs with men, etc. It's easier for a vtuber than IRL idols but yabs can and do still happen (example, Rushia) so still an important quality to keep in mind deep down
-growth: one of the most important qualities, this type of idol needs to start at one place, and grow to new heights. Better singing/dancing, entertaining, collabs, and have their star power shine bright.
There are some JP holos that are this, a few EN holos who have some of these (Gura/Irys), but only 1 EN holo that has all of this:
Kiara.
