Sounds like Azuma, Masumi, and company had an awesome night out the other day. There are more tweets between the various other people involved, but I gave up on translating all of them.
At the bottom Azuma is talking about having an endoscopy. There's a phrase in there, 痛くもない腹を探られました which my dictionary says means "To be wrongfully accused." It literally means having someone probe around in your stomach. I think Azuma is speaking literally in this case since he's talking about an endoscopy, but there may be some connection to the idiomatic meaning when he talks about it being like torture. Or maybe it was just really painful.

Azuma-sensei actually got played with by a dog, bitten, washed, had his growler, and was operated on. Sorry we all barged into your office like that. I had a great time seeing your rough drawings.

The 6 of us going out to eat after work yesterday, then stopping by Kiyohiko Azuma-sensei’s studio to hang out, followed by a trip to Takashi Shiina-sensei’s studio, made for a wonderful evening. I had so much fun.

@masumi_asano Thanks for the fun evening, it was a blast! Azuma-sensei was really nice and friendly. I’m jealous of how you get doted on like you’re a relative’s kid or something (laugh).

@Takashi_Shiina Thanks for everything yesterday! It was so cute to see you get so excited over Azuma-sensei’s draft, even though you’re a manga artist yourself♪ I’m going to keep using my status as “relative’s child” to get spoiled by Azuma-sensei, and to get you to make me tako-yaki!!

@azumakiyohiko
@Takashi_Shiina Thanks for being such a gracious host yesterday. I was amazed that you would show me your original drawings when I was a visitor in your house. Maybe it’s because of your 4koma series Shiina Department Store, but I think of you as a kind of 4koma veteran, so getting to see your manuscripts was a real honor.

@Takashi_Shiina
@azumakiyohiko I should be the one thanking you. Sorry for barging in on you like that. We’re in the same neighborhood, so you should stop by to hang out once in awhile! Next time let’s go out to eat with Rumiko Takahashi-sensei!

@azumakiyohiko
@angela_atsuko Thanks for setting them out. I had fun getting wrapped up in that strange gathering yesterday. The next time I draw, I’m going to do it listening to “Angela Matsuri”

@azumakiyohiko This is the writer Ookouchi. Sorry for dropping in on you unexpectedly last night. I ended up having a great time. Thanks to Masumin as well. We totally need to do that again.

@azumakiyohiko
@ichirou_o Thanks for yesterday. You know they also do endoscopies where they put you under. They were poking around in my stomach while I was still awake, like I was being tortured. We should talk again soon.

@ichirou_o
@azumakiyohiko I’ve had them done twice while I was conscious. One through the nose and one through the mouth. It was really awful, and after I talked to them about it they gave me anesthesia. When I was asleep, it was over in an instant. We really should talk again soon.
