I checked out the web novel:
These girls will arrange (demand) dates with him one by one. But after that, the protagonist is done with them (he wants nothing but grind in dungeons for the whole novel).
They will meet Maria and this team at the tournament. After that it will need to save her in Vladivostok (in the dungeon), then when she calls to meet her parents in Moscow, he escapes and she no longer appears in the story (this is not accurate as I after 150 chapter just briefly ran).
After that, there will be other women and the cherry on the cake - getting into the fantasy world (another batch of fan girls). After defeating the Demon Lord, his level will increase by 710846 and a portal to our world will open. The End.
It's not until the second half of the novel that the author realizes that there may be criminals using level and unique skills. Honestly, it annoys me that the setup isn't bad, but the implementation is poor. Especially after X-Men, where these themes were presented a thousand times more interesting.
