A bond once broken can always be restored. A romantic visual novel starring, and produced by, Minato Aqua from hololive.



I want to be a real maid heroine! AQUARIUM is the first visual novel produced by hololive's Minato Aqua.

Become Teo François, the oldest son of a noble family,
and say hello to your new maid Aqua!
Let's hope she won't mess up all too badly between her cooking,
cleaning, and laundry duties...

Set in a European fantasy world, this is the sweet yet emotional
tale of forbidden love between two souls reunited.

This work was created out of Minato Aqua's dream to be
an actual maid in her very own story.
We invite you to become her master and grant her that wish.

This is the summer story of Aqua - a beginning maid carrying a secret - and her master (the player) who lost part of his memory.

The young Master, heir to the François family, has the same nightmare every night.
In it, he meets a girl, but they always end up quarreling and parting ways with the words "I hate you" ringing in his ears.
But just who is this girl...?

One summer's day, the young Master's elder sister tells him that in order to prepare for succeeding to the François family estate, he is to practice his leadership abilities.
To do that, his sister wishes for him to take a new maid under his wing so that he can guide and help her grow.

I am the new maid, Aqua. From today, I will be responsible for your well-being, Master.

The young Master immediately finds his heart drawn to Aqua, the new, clumsy maid who is burdened by a certain "secret" she cannot speak of. However, the two are separated from one another by an insurmountable wall—their social strata.

What shadow looms over the two as they face challenges and the opposition of society itself?
This is the pure summer love story of two individuals from completely different walks of life.

If we become lovers, they might try to forcefully separate us... Then we might never be together again.
