Wait for it!
Don't wanna spoil anything but let me tell you this gate in japan will change our whole worldview of this story...all I can say is just wait.
Things get Infinitly more interesting in the future. (A lot of important plot points have not been introduced yet, and I mean A LOT)
Sincerely,
Someone who read the lightnovel
it's satisfying to see him breeze through difficult events alone and shock everyone but bruh at this point his summons are more relevant than the side characters in this story. i hope this changes as the story progresses but i highly doubt it will :/
