Story
This is the story of Jinkyung, a shut-in with social anxiety problems who gets summoned by a novice Summoner to her world. He is faced with a mountain sized insect Demon and the ridiculous task of defeating it... yet he somehow manages to easily do so. Jinkyung has been pulled into a world where giant Demons are an every day sight, magic is reality and where he has immense power.
An incompetent duo which somehow obtained immense power... will "Lord Yutaba" Jinkyung be able to save the world? Is there any real challenge for his newfound power? Will he be able to overcome his social anxiety?
Power
The verse is relatively new, but its already pretty high power wise. Starting with mountain-island level power since literally the first fight and with pretty much every relevant Demon ranging from building to mountain sized and to even higher, the verse hit hard off the bat. Even lowest tiers of relevant combatants have forms to fight lower to mid class Demons.
But that was just the beggining, we eventually get revealed that Jinkyung's power is likely more or less something between magical powers and reality warping which makes him essentially a Deus Ex Machina capable of assigning powers up on the spot upon meeting a few criteria. And with the fight against Kaltovia of the Dusk we meet that island+ sized foes and likely even larger are to be expected. But dont judge a book by its cover, size isn't the only attribute to these enemies, island level power is a pebble to beings like Kaltovia. During this fight FTL attack speeds and at least Planet level destructive capacity were shown by Jinkyung (who literally accidentally destroyed a planet in seconds after an attack dodged by Kaltovia flew into space), and Kaltovia proved a match for our protagonist up to that point.
Thus after recent chapters it has become obvious that our MC isn't the only overpowered being in the verse. With the story being in its early stages and with Planet or higher level power already shown, there's still room for the verse to become even stronger. Specially given the fact that even the protagonist knows very little regarding his own powers and that beings even above the likes of Kaltovia are still waiting in the verse.
