Free suspense adventure game"To my dear [Name]"This is a work by "Satsuki no Yume," who created it.
It was a suspenseful adventure with mystery elements that cleverly utilized a science fiction setting.
There are three bad endings and one happy ending, and it took about an hour and a half to see all of them.

Game Overview and Impressions (No Spoilers)

The protagonist, Itsuki, a second-year high school student, and his best friend Akane decide to try a magic spell before going to sleep to find out what their future selves will be like in 10 years.
Itsuki didn't believe it at first, but when he tried it that night, his consciousness was transferred to the body of his future self, ten years later.
However, ten years later, I somehow found myself in a burning cabin, handcuffed with a mysterious man.
Suddenly, Itsuki's consciousness faded, and he found himself back in his original body.
When I asked Akane about the results of the spell, she told me that my future self would be dead in 10 years.

Why is Akane dead 10 years later?
Why was Itsuki inside the burning hut?
And who exactly was the mysterious man who was handcuffed?
These kinds of mysteries are presented, and the story progresses.

The game is a fairly standard adventure game.
The story progresses primarily through conversations with characters and exploration of the map.
There are a few puzzles and mini-games along the way, but none of them are difficult.
Additionally, certain actions and choices made along the way can influence the ending.
Saving frequently in separate save files will allow you to progress through the game more efficiently.

What stands out in this game are the beautiful graphics of the characters and the event CGs.
I personally love the art style, so just looking at the cute and cool characters is a treat for the eyes.
Also, the lively conversations between the unique characters, including Itsuki, are interesting and I think they are one of the highlights.
It's more of a sci-fi suspense adventure than a mystery, but it does have the thrilling deduction scenes that are the essence of a mystery.
It's a game that can be completed in one go, so if the story piques your interest, why not give it a try?
The game has a great pace, so if you get drawn into the story, you'll probably end up playing through it all in one go, like watching a two-hour TV drama.

There aren't many difficult branching paths, but it's a good idea to refer to this if you get stuck.
Review (contains spoilers)
The following contains spoilers for this work.
The spoilers I write are limited to this work only, and I have made sure not to mention anything related to the other work, "Dear XX".
Please be aware of this.
Well, I really enjoyed playing this game, "Mirai Kagami."
The first ending I saw was "Bad end 3: An Unchangeable Future."
During my first playthrough, after picking up the notebook, I ended up talking to the club president before I could talk to Iori-senpai, and that's why I missed my chance to return it.
I didn't expect this to be the condition for the ending branching, so I was actually excited that it was a bad ending where the future doesn't change, even though it seemed like a happy ending.
During my first playthrough, I was wary that the person who looked suspicious couldn't possibly be the culprit, so when they turned out to be the culprit, I was a little taken aback.
However, after seeing Bad End 3, I felt even more motivated, thinking, "Yes, that's right, it should be like this."
My theory was that Iori-senpai appeared to be the culprit, but the real culprit was Itsuki himself.
The motive is that Itsuki himself has feelings for Iori-senpai, and he wants to sabotage their relationship.
In fact, ten years later, Itsuki sends Akane a letter telling her to break up with him.
Furthermore, I deduced that the harassment that Iori-senpai's partners end up receiving is also something Itsuki is doing.
In the end, judging from the happy ending, it was simply concluded that Iori-senpai was the culprit, so I was just overthinking it.
While the artwork of "Satsuki no Yume" is beautiful, there are also quite a few frightening depictions, which is one of the things that I find so appealing.
The single image and depiction of the scene in Bad End 2 where Itsuki is buried alive was terrifying and created a great sense of despair.

My favorite character in this work was the protagonist, Itsuki.
She has a straightforward personality, no weak or effeminate traits, and can be audacious and calculating at times. She comes across as a down-to-earth, unpretentious person, which made her seem very vibrant and authentic.
Mutsumi and the other members of the agency are all great characters, so I'd love to see another story featuring these characters in action.
