「む・・・迎えに来てくれて・・・有難うお兄さん・・・」

「なかなか居ないぜ。あんたみたいに、傘をわざわざ取りに来るお客なんてさ・・・。・・・今度は無くさないように気をつけろよ。」「「「見つけてもらえてよかったね～」」」「あ・・・みんな・・・。ごめんね。私だけ、先に見つけてもらえて・・・・、あ・・・あの・・・お兄さん・・・。出来たらでいいから 、みんな引き取って・・・」「いや、それはいいぜ。他のやつらは私がなんとかするからさ。お前は取りに来てくれた、持ち主の事だけ考えてればさ・・・。」「「「そうだよ～」」」「・・・みんな・・・。うん、有難う。・・・・・・・お兄さん、忘れられた傘はほとんど取りに来る人が居ないって聞いてたから・・・このまま捨てられるかもって・・・怖かったよ・・・。これからも、私を、傍に置いて、使ってくれるかな・・・・？」

Thank You... for Co... for Coming Back to Get Us, Onii-san...

"There aren't many guys like you around; a customer who'd go out of his way just to come back for some umbrellas....... Be more careful so you don't lose them next time." (In unison) """We're so happy that you found us!!""" "Ah... everyone.... I'm sorry. He was only looking for me.... uh... umm... Onii-san.... if it's all right with you, can you bring everyone—" "No, that's just fine. I'll figure out something to do with the others. When you think about it, coming back to get you was my duty as your owner.... (In unison) """That's right!!""" "...Everyone.... that's true, thank you........ Onii-san, forgotten umbrellas always hear that there aren't any people who ever come back for them so... I thought I might have been thrown away... it was really terrifying.... From now on, will you always use me and keep me by your side....?

In the other pictures, the Kogasa clones are Kogasa and Anon's kids.
Apparently, in this pool, they are all different umbrellas. All looking the same for some reason.
