Because they are obviously not the leader/royalty?

Looked up the wiki page for the maps after reading one of the above comments about the skillblooms. Are they random drops from the event maps? Or was that just during the past event? Getting a 5 star unit this easy is nice but a bit lackluster if no way to upgrade her without wasting crystals.

RNG Chests in maps I presume as the wiki said. Like, Manyuu dailies or Dragon dailies or even the SG Manyuu or Amphys in stage 12 and above. Most will have a chance of obtaining Golds and this one is no different.
