He did try it already, when he first discovered that it worked like a portal was right after acquiring it. He crossed over from the USA to Korea o fight that pink haired Team Leader from Haesun/Haesung(??) However, after that I don’t think he had any reason to use it, he still brings his clones to him through the skill but he himself just hasn’t had a reason to use it after that first time. He might also be using it but the writers just don’t put it in cuz it’s not relevant to the story. The only reason I remember where he needed to use it was when n.2 was kidnapped, although he took over and tried to use it, their connection was forcefully ended and so he couldn’t use it. ╮(￣▽￣)╭
It's such a fun skill I want to see it more this school arc is kinda boring imo
I forgot but his spatial distortion storage skill can't keep living things but can keep the clones? And since it's a single shared space when multiple clones and himself are using it the spatial storage becomes more like a Portal right? Why he isn't using it to go to the places his clones are is it only the clones who can use it as portals or he can too I don't remember if he tried it already
