Hmm...lemme take a stab at it what she's saying...
(From left to right) Wh-...are you really sure this is alright? You can probably get more girls cuter than me, y'know! ... Um...uh... If it's fine with you... ...then me too?
OK, listen, I don't have the art ability to make this myself, but THIS is how a Marisa confession should go:
Marisa: "Hey, a confession? Cool! Why don't you go say "hi" to all the others who confessed?" (Heh heh, Reimu is gonna be SOOOO pissed when she sees how many more confessions I've gotten.) Alice: "He- Wha- ANOTHER Confession? Where do they keep coming from?" Patchouli: "Well, at least it's still not Rinnouske... yet." Nitori: "Should I, like, make an expanding bed or something that can handle this many people?" Flandre: "Oh wow! I get to live with this many people? It'll be so much fun!" Koakuma: "P-Please stay calm, miss Flandre!" Alice: "Wait, why's Koakuma here?" Koakuma: "Umm... Mistress Patchouli is going, so I came too." Patchouli: "I figured the best way to get my books back was just to start living together... what does "borrowing" matter when we live in the same house?" Alice: "Then... what about these other people?" Kogasa: "Eh? Um... Miss Marisa said something about a magical item, grabbed my umbrella body, and I just followed... I mean, it's the first time someone actually wanted to have me, so..." Mystia: "AH! She drove away that scary ghost woman when I was in danger, and if I stick around her, maybe I can live in peace..." Wriggle: "... She actually makes me feel like... a woman..." Nameless Fairy 1: "When I saw so many people, I managed to get my courage together! Confessing made me feel so... so... important!" Nameless Fairy 2: "I know! It's like, we were rising up the ranks to become a supporting character!" Nameless Fairy 3: "Maybe we'll even get NAMES!" Okuu: "Unyuu?... Why am I here, again?" Rin: "I'm watching over Okuu." Satori: "... I got bored. These people have such turbulent hearts, it's kind of fun to read. Say hi to the ever-more-excited lolicon who just joined for me."
(I tend to see Satori as Hanajima from Fruits Basket...)
...Ugh... T-......
If that's how ya feel, I guess...
...it's fine ze ?Wha-...!
Ya really OK with this...!
I'm sure there's a lotta girls out there cuter than me!
