I really adore her! I've always had this kind of special fondness for the really quiet reserved types, and I think Mutsumi is a compelling twist on this, especially in the context of Bandori (she feels totally different from, say, Rinko).

She's the kind of character who you just want to reach through the screen and hug, I remember the first time I watched It's MyGO I was just constantly thinking "I need Mutsumi to have a good day maaaaaan." I also like the gap to her that we saw from the karaoke scene, and that in many ways, she's truly the thing that bridges MyGO and Ave Mujica throughout the anime. Her dynamic with Sakiko is really interesting too; Umiri's line asking if Mutsumi truly wanted to go through with this kind of haunts me at night. ALSO THIS THING YUNIKO AYANA SAID ABOUT HER: "the Mutsumi line was the final nail in CRYCHIC’s coffin, and she said it because she didn’t want Sakiko to bear the burden of breaking up the band all on her own. Breaking up the band was Sakiko’s idea, but Mutsumi saying that dealt the final blow in ending things. Mutsumi will have to bear the burden of that sin."

I feel like I can't talk about Mutsumi without also talking about Mortis, so I'll also add here that Mortis' commentary from Quaerere Lumina was my favorite. She seems so lost and broken and the implication that she's aware that she's a doll but she wasn't put together right just hurts. I also really loved the moment where she "broke" Amoris' arm, and how unhinged Yuzumoon is on stage as her. Also her crying for joy when the world was destroyed and being jealous of it was just?????? OKAY. She has that kind of quiet but terrifying force to her (which also applies to Mutsumi off-stage, I feel). The ways in which she feels lost and clings to Sakiko/Oblivionis because she doesn't really have anywhere else to go drills in a lot for me in regards to why she was in Crychic in the first place.

In any case, I'm very excited to see her in the upcoming anime! Yuzumoon's been doing great work with her and I'm excited to hear the moments she's been hinting at for us.
