Fun fact about me: I LOVE Monomi/Usami! 
She's a very special character to me. I guess what a lot of people would colloquially refer to as a "comfort character". As such, I've collected many plushies of her...because what better merch to buy of a stuffed animal character than literal stuffed animals?
I'll be delving into all of my Monomi plushes, along with every bit of info I can find on them. This list will be ordered by release date, so if I acquire a plush that was released earlier than some of my later enteries, it will retroactively be added before those enteries. I will make sure to include an "added" date to avoid confusion.
With that...let us begin!

Date added: 22/10/24
Here we have the FIRST ever released Monomi plush. How do we know it's the first ever releaed? Well...because it was made before SDR2 even came out. This Monomi plush was made as a pre-order incentive, meaning buyers got it the same day SDR2 officially dropped in Japan. Can't get any more "first" than that.
Model Number: N/A
Company: Spike Chunsoft
Release: 26/7/2012
Unit Price: 8190円 (normal edition) ~ 11340円 (limited edition)
Height: 10cm
As for the plush itself, the gimmick of it was the fact it could speak. Inside is a speaker including 3 set phrases from Monomi used in the final game. Below are three sets of audios. One recorded from the plush, one taken from the actual game, and one taken from the official English version of the game. Personally, I think the choices for the lines are a bit...odd. A lot of them are the lines that were showcased in the promotional trailers, so I suppose it makes sense from that standpoint. Otherwise, I would have really preferred "Love, love!" and suchlike.

Below are high-quality scans I took of the packaging she comes in, both front and back.
Finally, let's have an in-depth look at the plush itself, courtesy of my bad photography skills.
I will be using a Pokemon card as a size reference for all of these plushies. As you can see, she is not only the first Monomi plush, but probably also the teeniest!
Not much to say in terms of build quality. She is soft, but has thin fur, which is to be expected on a plush of this size. Let's look at some more interesting close ups.
I'm sure you're wondering what this yellow stuff is...it's glue! Again, not surprising to see on a plush of this size. Considering the age of this plush, even though I bought her brand new, the glue has yellowed with time.
If you recall, Monomi has a pale yellow bow, not a pink one. This, and the early prototype of another Monomi plush we will discuss soon, are the only official Monomis I've seen with pink bows. I believe this is an indication that Monomi was originally going to have a pink bow. It is not uncommon for companies to give out design sheets to manufacturers to start production on merchandise early. So, when the design ends up getting changed, it's too late on the merch front. This is the reason behind the blue shirt Bart Simpson phenomenon. I believe the same is occuring here.
What a cute little pre-order bonus! Down below is the final photo I took. She looks right at home next to a copy of SDR2 and a PSP.
