I'm guessing Konngara is pondering over the whole: 'we need to think of a better plan I guess', whilst they talk they eventually come to a conclusion of calling Suika to help them with that matter, but lo and behold Suika really does appear to them.
S1eth said (in the previous strip's comments): With Suika's ability to gather all vengeful ghosts in one place, this doesn't sound like a difficult task.
Looks like this might be what's happening after all...
'S the big idea?!...in order to prevent damage befalling outside of here......why would Yuyuko be sacrificed in the first place...?I see now!In that case...Hmmm.Suika-dono!This voice......when I'm not around?Yo!...if we erect a barrier to seal in the vengeful ghosts temporarily....... If I could do that...Talkin' bout fun-soundin' stuff like that...Long time, no see!
