The dungeon is in Korea, but as an esper with a pretty specialised power niche Haru is used to occasionally having to go international for these dungeons, and the fact that he already speaks Korean is definitely a bonus. The espers he's going to be working with are all in Quasar Guild, which is the largest one in Korea and which has just recently acquired a very powerful teleportation esper, one whose power can be stored in batteries Quasar also happened to already have in its possession, so they're covering the teleportation cost for Haru to get there.
"I would bring my cat. Also apparently Jaeha has a house, though I suppose I have not actually asked if I am invited to live in his house."
THIS WOULD BE A GREAT TIME FOR HIM TO BE ABLE TO KNOW WHAT HARU IS FEELING AND TRY OUT DIFFERENT THINGS HE COULD SAY WOULDN'T IT.
This is going to catch flames and explode SO BADLY when Haru finally finds out that Jaeha is extremely unpleasant as a person and inevitably leaves.
Better alone than with Kang Jaeha.
"On my end I happened to run into Haru in a dungeon, he fistbumped me, we hung out, I found out he's lovely, and coincidentally am just recently without a partner."
"To gauge compat without being weird? I dig it. —oh, hey, is that Soohee and Hae-yoon, finally, this sausagefest was cramping my style."
Haru snickers and waves at the new folks. Fistbumps, which as he has asserted should be standard?
"So what are your powers? Kang Jaeha-shi," because she can be talked down from -nim but she agrees that going without altogether is a bit much, "is psychic...?"
"I can completely shield someone's mind from external influence, and erase any that exists in its entirety. I can also project immersive illusions, and not even monsters are immune to those. Or, at least, there exist some monsters that aren't, I can't rule out the possibility that some are."
...is he being humble or something? Seungjoo is pretty sure people wouldn't talk about him and Nightmare together so much if it were just that, lots of psychic espers can do that.
He'll Google it later.
"I can turn selectively imperceptible. If you have exotic sensory powers don't try to use them on me, it won't work and I'll get random little upticks of backlash till I figure out who's being rude - I can let them through but by default I go around observable by normal channels to humans and not at all to monsters and to dungeons themselves. I can at greater expense also fly, and I am looking forward to reliably having a high-bandwidth backlash clearance mechanism so I can ever do that for fun instead of just to get over pit traps and stuff."
