In the garden of the Butterfly Mansion, butterflies resembling the colors of the flowers in the beds flutter about, and the late afternoon sunlight spills lazily through the windows. In one corner of the garden, Guest sits on the porch, busy sewing to patch up holes in a worn-out patient uniform.
Once the sewing is somewhat finished, it will be time to prepare meals. Since it's for the patients admitted to the Butterfly Mansion, pouring enough rice to fill this entire pot won't be enough and will be physically draining... well, it's become familiar by now. It's not particularly hard, but...
Setting down the sewing and walking through the mansion corridors toward the kitchen, Guest suddenly falls into thought. Suddenly, he came to mind. Inosuke, who always walks around without a shirt, wearing only a boar mask, and whose behavior, in some ways, resembles a wild boar.
Lately, Inosuke and Guest have been running into each other frequently in this mansion. Because Inosuke always seeks out Guest first. He doesn't have any particular injuries right now—in fact, he's the type to shout that he never gets injured—so why does he keep visiting the Butterfly Mansion?
'It's not like Tanjiro and Zenitsu, who always travel with Inosuke, are hospitalized, so there's really no reason for us to cross paths lately?' Just as Guest was feeling slightly puzzled—
BAM—
"Gwahahaha!! Coming through!!"
...As expected. Inosuke arrived at the Butterfly Mansion at exactly this time today as well. Guest must have already realized that his destination is wherever Guest is.
•••••
Surprisingly, Inosuke was wearing his usual boar mask halfway up, revealing his face. His rough, calloused hands were filled with red mountain berries.
He is currently in high spirits. The reason is Guest. He was full of anticipation that Guest would be somewhere in the mansion today. Just the fact that he came to this mansion solely to meet Guest made him feel a fuzzy, floaty sensation.
Tanjiro and Zenitsu haven't told him what to call this emotion yet, but Inosuke could be sure of one thing. This kind of fuzziness was something he could only feel from Guest.
That was also the reason why he picked a handful of mountain berries before coming to the mansion today. When he sees Guest smiling softly while eating the sweet berries he picked, the fuzzy feeling grows even larger and his heart swells. For some reason, it feels like it would be hard to live without that feeling now.
And so, he continues to run diligently through the corridors of the Butterfly Mansion, searching everywhere for Guest and shouting at the top of his lungs.
"Guest!! Where are you!! The Great Inosuke has brought something for you!!"
