Shwoof

Kasen slid open the doors to the Hakurei Shrine. It had been quite a while since she had checked up on the current shrine maiden, and as the most recent incident had been solved for a while now, Reimu was less likely to immediately kick the hermit out of the shrine.

Whether or not she would listen to Kasen's suggestions was a different story, but eh, baby steps.

Entering the main room of the shrine, Kasen spots Reimu sitting at her kotatsu, chewing on... something. The miko looked up, and her pensive expression turned into an exaggerated grimace.

"Oh, it's you. Come to lecture me again?"

Kasen ignored her, instead looking around the shrine. The walls lacked any holes, the pit that usually held an endlessly burning hellfire was filled in, and that godforsaken leak in the ceiling was finally fixed.

Really, the only thing off was some specks of some sort of rainbow colored material dusting the floor around the tab- wait a minute.

"Reimu, what are you eating?"

The miko blinked, before holding up a multi-colored orb from underneath the kotatsu. The sphere glimmered softly in the afternoon sunlight. It also had a large bite taken out of it, making it look like the logo to an outside world company that shall not be named.

"One of these things. That centipede youkai in the mountain said it tasted enough like dragon meat, so I figured it was probably safe to eat. I haven't tried dragon, yet." Reimu explained, bits of the orb falling out of her mouth as she spoke.

"Finish chewing before you speak." Kasen chided absentmindedly. Reimu swallowed the rest of the material in her mouth as the hermit looked on in awe and fear. Slowly, but very deliberately, she brought an arm up to her face.

"Close the door behind you, would you?" Reimu suggested, having finished her meal.

"Reimu, that's Rainbow Dragon Ore. That's literal metal."

The shrine maiden looked at the orb again. "Huh."

"Not to mention, it's some of the rarest material in gensokyo, on par with Morkite or Netherite." And also common sense, but Morkite was a lot more useful.

Crunch

" Reimu."

"What?" She asked, bits of the very rare and inedible ore dropping out of her mouth, "There was a ton of the stuff in those poisonous mines. Can't be that rare."

" Poisonous mines?"

"And close the door already. It hurts to look at this in direct light."

Kasen could just feel her day getting a whole lot longer.
