Ahhhh, I think I get it. At first I didn't understand the comic at all and that murasa is just being a jerk, while that still stands true I did a little of bit of searching and found out that Ichirin had won a water yoyo from that little game of Yo-yo Tsuri (assuming my information is correct) and after she had gotten it Murasa, I'm guessing, manipulated the water to expand rapidly therefore popping Ichirin's prize which is why she's looking so heartbroken. Feel free to correct me if what I said is wrong but that's what I think is going on.
Also, let it be said that Ichirin without her hood looks very beautiful. I believe in tani takeshi's 4koma where Osa-Ichirin managed to take off Ichirin's hood I swear she looked like Hijiri because of how long her hair is in that comic.
