Soul Domain

"Hoooh~" Robin's mouth gave an 'O' shape as if he was giving a long exhale but no air came out, he then laughed out loud, but no sound came out.

His body itself seemed that it was made out of the smoke, and although that strange smoke body was full of holes, the features of Robin's face could be seen if one looked closely at it.

Robin's loud laugh turned into a big smile that appeared on his face as he looked at that huge thundercloud for a few more seconds, then his smile disappeared his smoke body closed its eyes for a few seconds... 

*Ploom*

Right afterward, the huge thundercloud started sending tentacles to hold onto Robin's image.

6 tentacles emerged from the thundercloud and touched 6 gaps in Robin's smoke body, then they began pumping something into those gaps

And although the pace was slow to be seen by the naked eye, those gaps were undoubtedly shrinking.
