Demon Slayer: Something's Off About the Hashira I Summoned

I transmigrated into Demon Slayer and awakened the “Pillar Summoning System.” I was ecstatic.

But then

First summon: Shinnosuke Nohara, who dances the butt dance at demons.

Second summon: Sasuke Uchiha, who thinks I'm weak and goes straight to Susanoo.

Third summon: Optimus Prime, who punches an Upper Rank demon into the sky, then gives a speech about freedom and justice.

Muzan Kibutsuji: “Just who are you?!”

I pull out some popcorn. “Just a passerby here for the fun. Remember that.”

[Everyone survives]

[Addicted to gacha]

[Fun levels through the roof]

Don't ask. Every summon is more ridiculous than the last.
