One day, when Nina and Nijiro were on a trip back to Planet Herby,
"We've finished it..." Nina was relaxed. They made an exploration of Planet Dimon in search of diamonds.
"Yes, Nina Chan... It's a fortune. We can mine a huge number of diamonds." Said Nijiro as he plunged into a pile of diamonds and crystals.
"With this diamond, the Supreme Master can continue his research," said Clori as it rubbed on a mast.
But suddenly, their spaceship was attacked.
Announcement from the System:
"Warning!!! The Spaceship is currently being attacked. Please do the wormhole process!!!"
"Oh, No... This isn't good, Nijiro Kun. The Sigron Pirate Space Fleet attacked our spaceship.
"Sigron Space Pirates?"
"Yes, they are a bunch of treasure robbers. Their targets are small ships that are not equipped with assault weapons." Clori explained.
