Sauce?

Bro, you're dangerous for our society!!

That's actually a good idea. You can just give it to your friends (especially girls) and when they ask, say blushingly, just say that you've thought about them when you saw this flower and if they really knew it's meaning or search it, it might be helpful to you get a girl and in case it fails and they ask about it shockingly, just say it's just a flower which reminds of them and has nothing special meaning. That way you'll be play safe(hopefully).

As some guy said in the last chapter it's either going to be wtf domain expansion : flashback or domain expansion : naruto talk no jutsu. Author used both domain expansion at the same time.

To break the link, they still need to confirm whether it's actually coming from moon or with some other method. Even if we consider some method from kaguya's people who lives in far in the galaxy or different galaxy(which I'm assuming), it'll still take light years just to travel even with the light speed. Nano machine's idea is also possible but it doesn't define how is it change her position from deep ocean/volcano to somewhere safe. I don't know but that part confuses me. 3rd thing is that you mentioned writing a virus which could backtrack the main server and break the link and NASA couldn't do it. Well, I assume he might be able to considering how far he has able to accomplish with only a bit of information and remind you, that he's still 18/19 years old. Let's see what author has come up to surprise us readers.
P. S. : as I have said in couple of chapters before, this is starting to become more like sci fi manga than romantic comedy. Though I love this.

If I'm not wrong, it was mentioned that tsukasa was backup plan for the backup plan to restore kaguya's memory or something and tsukasa's is stored wrt moon. Again, when they say if you destroy the moon so there might be a chance to destroy that backup and that immortality tsukasa possess.

Yes, sure.

I wanna do that as well.

That's probably one of the answers for her ability..

Me as well..

I agree. Even that working person is either holding their laugh or getting embarrassed after watching this.

This just showed that he's still human and that's very natural thing. Some people will still call the mc loser or something because he hesitated after seeing that scene for the first time.

Is there any cultured stuff as well?

Wow, how much do you watch cultured stuff? Seems like it's clouding your thoughts..

Umm yeah? What does it look like to you?

A cultured person's bike.

Yeah, it did. Also went through last few chapters as well.

Well, combining all 5 of them, I doubt there's anyone in the story who can defeat them.

Thanks for the explanation my friend..

That also when his partners are 4 S rank adventurers who's supposedly even stronger than ceres.
