Anyway, Wavygyaza's brain is connected to the Neo Hero main servers and here she felt that Isamu was hacking into them, which is why she looked at him like that
And that's why Isamu comments Suiryu "saved him" with his intervention
In any case this is an interesting development because Wavygyaza brain being directly connected to Neo's database is manga only and makes her lose a lot of autonomy compared to the webcomic and in the webcomic she was pretty much a puppet too. I wonder what ONE is planning with this.
