BUR #30169 has been approved by @nonamethanks.

create implication ys_altago -> ys_seven

mobile spinoff of Ys 7

BUR #30170 has been approved by @nonamethanks.

create implication ys_iv_dawn_of_ys -> ys

one of the Ys 4 games.

I should at least mention this game has different designs and art style to the remake Ys Memories of Celceta. so this tag doesn't need to be bunched up or alias'd to Celceta imo
