One day, I was suddenly summoned to another world. After successfully fulfilling my role as a hero in one year, I returned to Japan.

I reunited with my stepsister, and that should have been the happy ending... but it wasn't.

To my surprise, my stepsister had become a VTuber!

What's more, she was the public relations manager for 'Little Brave Online,' a VRMMO that was attracting worldwide attention!

To shower my stepsister with items, I immediately bought 'Little Brave Online' and started playing.

The world certainly has levels and stats, but more than anything, it's a world where personal skill speaks volumes.

While many people struggled with combat using swords and magic, I, who had already mastered such combat, dominated with the fastest clear and continued to shower my stepsister with items!

This is the story of how I shower my stepsister with items.
