BFB-ronpa: Inanimate Massacre

[I] "Dear diary..."

. . .

God, I feel so sick.
One of us is dead, and one of us killed her.
I want to find out who did it, but how?

I felt my Monopad rumble and took it out. It showed a notification. "Monomono Files" It said. Huh... I clicked on it.
It showed some crucial information about the murder, even with the time of death. It also showed a portrait of Teardrop in black and white, with some hot pink circles on her torso and head. The info states:

Teardrop Lavaliere was the victim.
The victim was found in front of the dorms, inside of the broom closet.
Cause of death:
- Estimated time of death is around 11:20 P.M.
- The victim was subjected to blunt force trauma and stabbing on the torso and right arm.
- The victim suffered from 20 stab wounds.
- No other injuries were reported.

It was really helpful information, probably have to keep them in mind. Me and Leafy cautiously went towards Teardrop's body, I kneeled down to inspect the body a bit. I noticed that her notebook was under her body, possibly fell off when I opened the door. It was soaked in blood, the pages had a pink tint to them. "What's written on them...?" Leafy asked, leaning down to see the notebook closer. "I dunno, let me read it." I opened the notebook and saw a blood-stained bookmark.

It showed an entry from yesterday, the last entry written by Teardrop. She wrote:

"Dear diary.
Someone gave me a note. I don't know who, since it was on the chair I was sitting on in the dining room. It said they wanted to meet me tonight outside. I'm scared. But they said it would be quick and i should come out alone i dont believe them. i dont want to go out im scared i dont want to die but im curious you know? i dunno, this might be my last entry here. hope that someone would read this, or maybe they would ignore it, i wish my family was here to protect me. i wish my friends were here to protect me. im sorry mom and dad i did a bad thing. a bad thing which i could not reverse. im sorry."

And another page.

"Dear diary.
im ready to go out, someone's there. i see them through the peephole. short, couldn't figure out their features. dont know their gender from what i could see.
maybe im just seeing things and its my sleep paralysis demon or something. im scared for my life rn my hands are shaking i scared but if i didnt come out..... what would they do? im risking it. im going. goodbye, dear diary."

. . .

She wrote... all of that... before going outside? It also said she was coerced into going out, we just have to find out who sent her that note, if... it even exists. I just kept the notebook for future use, sorry Teardrop.

"Hm... her body is starting to cool." I heard Tree mumbling, gently checking the temperature. "She has been in there for few hours. I'm not exactly sure though." He inquired. "I'll carry the body to the infirmary later." He carefully flipped her body over, and saw a bloody wound on her head. "... So that's where she suffered blunt force trauma." I spoke up.

I looked inside the broom closet, it was possibly the first time I took a closer look in there. I think this isn't an actual broom closet, since there was electronics, spray paint, and... a bloody baseball bat?
