To put it shortly: the main antagonist killed the player character's adoptive daughter.
To explain it a bit:Aleph-1 is the major antagonist for the current story arc of Wuthering Waves. Aemeath, a character who was positioned as a daughter figure to the player character, sacrificed herself to seal Aleph-1 behind a cosmic "gate" that would prevent it from causing worldwide destruction. As of the current patch of the game, the real Aemeath is still considered dead, and what's left behind is a puppeted body in effectively a vegetative state.
It marks a bit of a deviation from how gacha characters are handled in modern day, that being waifu/husbando bait with zero chance of facing any real consequences or stakes in the main story. Aemeath is instead written with a heavy focus on a parent-daughter family angle, being proud of raising a strong kid that ends up taking after you too much, and the grief of losing them (the events leading up to her exit from the story continue to affect the player character's thoughts and actions in new story).
@Ascendant_of_DawnAs a scientist, he helped invent Gears, which turned out to be bad. Also, as the first Gear, a prototype, he wasn't under anyone else's control, so he's the only one that really feels any guilt as he's a lot closer to human.
Canon event: as remnant cubes for the major anniversary event (we're getting another edition of Second Coming of Solaris!), Shorekeeper Cube watches Phoebe Cube roll some dice.
Naturally, it's always best, when finding a live, disembodied ass-in-a-box in a dungeon, to proceed directly to putting your most sensitive bits in it, because of course it's safe, right?
Not only cool, but also now submitted to Hilarious in Hindsight because Teio is also in the Umamusume x Makibao collaboration that debuted on April Fool's Day:
Tagged just about everyone. As far as I know, there's no name for the muscular fox-thing wearing a crown, so I'm removing "character_request." If I'm wrong, please do add the creature's name.
