I was Reincarnated as a Side Heroine in a Yuri Game, and with all my Power I will Protect my Favorite Character

Chapter 1: I remember a lot.

It was then I realized I love Yuri.
Not the flower, but the genre, the genre where girls love other girls.
Furthermore, the relationship does not have to be romantic.
Whether it’s simply friendship, rivalry, jealousy, or envy.
It’s all okay as long as strong feelings from women collide.
If anything, I could still enjoy it even if it is an unrequited love.

Despite being a girl, I love Yuri more than eating. 

It was a week before I entered the new semester of my second year of high school that I remembered the memories of my previous life.
My cringy life as a serious Yuri otaku with a painful desire to see it all.

The trigger was watching a late-night anime on TV.
An anime that I don’t often watch, but it showed a particular event.
At the moment I saw a kissing scene between two girls it all came back.
The dirty information rushed into my head.
As expected, being a serious yuri otaku was really revolting to remember.
But why then, does it feel so right.

However, that doesn’t matter at this point.
The problem is something I noticed with the knowledge of my past life.

“.
.
.No way.
I’m, “Shiori Sugimura(杉村詩織)!””

I absorbed yuri from all over the world! In my previous life, I ravagedly pursed Yuri words regardless of medium.
2D, 3D, anything, but my favorite work is called “Fragmented Rhapsody(未完成ラプソディ)”

The protagonist is “Aoi Shinamoto 島本葵“(Obviously a girl).
She enrolls in Yurinomiya Girl’s High school(百合ノ宮女子高校) and could fall in love with her childhood friend, or a Senior in Club Activities, or a mixed race girl from another school.
It’s a pretty standard plot for a dating simulator.

Although it was a doujin game, it had as good of quality as any commercial work.
You could enjoy multiple endings where likability fluctuates depending on choices and the story changes based on the flags you set.
Moreover, the art is cute.
It’s amazing.

And the name of the senior in the club is.
.
.Shiori Sugimura.
Aka me.

She belongs to the art club in Yuri Nomiya’s Girl’s High School.
Barely a Second Year Student.
Long Half Up fluffy black hair, and a well kept appearance.
A clean face, and large breasts.
She was the mischievous older sister character.

“No no no no no, this is too weird! What am I a character in a video game?!??! I mean, I have memories of my previous life until it suddenly stopped at the age of 26, but when did I die!? Did I really devote my life to Yuri and die without even falling in love?”

After graduating from a decent university, I became a math teacher at a prep school while also working as a tutor as a side job.
.
.Why! Geeze, it wasn’t that I wasn’t popular at all, but did I live until I was 26 and die without even falling in love.
That’s so disappointing.

“But if this is really the same game world, then I will meet the protagonist in the near future.
And there is a possibility that a coercive force of the game world will happen and force me to fall in love with her? That’s a little.
.
.”

In my previous life I loved yuri, but I wasn’t gay, and I’ve never seen a girl in that light.
I had few crushes, but I wanted to one day fall in love with a gentle handsome man.

Above all, the main character is a strong guardian character, but I don’t want to get involved at all.

Oh yeah, the Protagonist’s childhood friend and the main heroine of the game.
Her name is “Koharu Wakashima 若島こはる” a character who has knew the protagonist since childhood.

If the story goes as normal then it’s highly likely one of the three Koharu endings will happen.
The other two are normal types, a happy ending and a bad ending, there is also a true ending.
But there is a significant gap in the contents of the endings.

It almost always appears when the other heroines have conflicting love flags raised.
They break each other and alter the story.
So they are often called “Flag Crushers” or “Iron Defense.” Among fans.
Most are light hearted bittersweet.
However, Koharu.
She is Aoi’s stalker.

There is a bad ending in which Koharu, who has become full yandere, pulls a knife and attacks the beautiful mixed girl form another school “Fujioka Sara藤岡紗良”.
This happens when Koharu’s love score is high while doing the Sara route.

There is also a bad ending with Shiori and Koharu.
But both end with a normal friendship ending.
For some reason only with Sara does it end bloody.
Why! Sara was my favorite!

Koharu is the demon-like guard.
In my playthrough I was enjoying the story, Little by little as Sara was getting closer, a murder event happened right after I thought it was going to be a happy ening.
My heart nearly stopped at that time.

I thought Kaharu’s obsession with Aoi was huge, but who would have expected the gentle homely character to be a Yandere? More over with the picture of crime.
It’s ridiculous! Who would want that!

“I don’t want to be inadvertently close to Aoi and be stabbed by Koharu out of resentment.
I’ll leave Aoi’s so her partner will be K
