LLINE age restricted for DH

Gonna keep it short.

So im trying to contact yarisugi circle thru LINE, but a problem arises, first that i cannot find a proper qr anywhere, even tho they state in the deli-fuzoku website they do under the news tab.

second is, gemini gave me an id for line to that shop, however it seems my line account, made with google, is age restricted, and even if it was a jp line account, i had to pass age verification. How come no one talks about this?

Yet i was able to add Robo Deli line with no issue, supposedly cause they do not promote themselves as adult services on line, accofding to gemini.

I would have used cityheaven but im having trouble with sms, last resort is going with mobal sim.

What my question truly was is how come LINE gave me such problems, and if maybe somebody can help me add yarisugi circle line

many thanks
