BUR #22732 has been approved by @nonamethanks.
create implication scarlet_(black_shadow)_(nikke) -> scarlet_(nikke)
create alias snow_white:_innocent_days_(nikke) -> snow_white_(innocent_days)_(nikke)
1. The former is the "younger" version of the latter, much like Snow White tag below.
2. This alias is to make it more consistent with other NIKKE's alternate skin/younger version tags, like the Scarlet tag above.
