A decent amount of machine translation errors in this, I've cleaned up where I can but I'll admit to not knowing quite enough kanji to fix things completely.
It used to be much worse though and things are *mostly* understandable though.
This is the last of akaishi shiroishi's works that I would have picked to translate. These copypasted images are his worst stuff and it's a nightmare to machine translate snippers of handwritten kanji. In most of his other work, he has a link to a text transcription which would make translation infinitely easier for you.
Also, if you really tried to fix this up as best as you can...you know you're allowed to rewrite the raw machine output, right? If two girls say "I am my sister", take out your mspaint eraser tool and replace that with "This is my sister". Even a certain amount of guessing and making shit up is better than just posting raw machine gibberish.
