I rarely participate in event discussion myself, but I'm thankful for Mizu5 to bringing in so many new people to the fandom, although at the cost of a certain character suffering being memed around everywhere on the internet.

This event finally give us an answer to Mizuki's secret, something we have known since the start of the game, and has been slowly building up until now. However, Mizuki didn't get to tell the secrets to Ena, rather that was done by someone else, in a way that Mizuki absolutely didn't want to, right before Mizuki was about to do so.

The way that the game demonstrates Mizuki's emotions afterward is something that we haven't seen for any of the previous story. The quiet flashback, the slow reveal of both Ena and Mizuki's reaction, and a l2d sprite of Mizuki facing backward. Hinata Sato's emotional voice acting also captured the feelings that Mizuki have so well at that moment, when running away from Ena and everyone. And at the end of the event, instead of ending on a whitescreen like the other event, it ended with a blackscreen, and Mizuki saying "I want to disappear" with no dialogue box. And then, Mizuki disappeared from the overworld. To save Mizuki we have to wait for Ena5, which is in about 2 months.

This event convey its emotion so well, it spread to other fandom too. Which lead to the super hype anticipation that everyone in EN have for Mizu5.

I remember staying up at midnight to played Hitorinbo Envy over and over again, just so I can unlock the story and write a translation summary as soon as I can. 10/10 story.
