"I have to admit, I feel a bit like you're just humoring me rather than telling me I'm not making sense," Haru Nagase sighs, wearing an extravagantly ugly sweater in place of his usual coat."
"No, no, it's not that at all," Tae Daigo says, hands raised up in supplication. A headband with felt antlers sits atop her head, a gift she'd had no idea of how to turn down. "Or, I guess... I understand the individual components, but not... well..."
"Not how it all fits together," Haru nods with understanding. "That's fine, I can take it all from the top."
"Oh," Tae says with all the hope of a crushed gourd.
Haru nudges his glasses up his nose. "Hashiramas is centered largely on the celebration of the birth of Hashirama Senju, of course, not just as an important historical figure but as a spiritual one. It is believed that he was the son of the Sage of Six Paths and inheritor of his will, and that in walking the earth as a mortal being once again he had returned in order to set humanity on a righteous path."
"Right, no, I got that part."
"Now obviously this was challenged by his friend, rival, occasional nemesis, and possible lover, Madara Uchiha, said to be the reincarnation of the Sage's other, meaner son, and while they worked together for many years they would eventually turn on each other, with Madara being defeated and... sort of killed, I'll come back around to that, but critically even after this battle ended Hashirama was robbed of the opportunity to truly bring peace to the world, and so passed on in order to live a new life and try again."
Tae just nods along at this point; it can be intuited that she is wishing for a second meteor to crash land in the village as soon as possible to kill herself or Haru instantly, the better to escape this lecture.
"So, in the darkest times of the winter months, worshippers will cut down trees and bring them into their homes in order to honor Hashirama and his powerful Wood Release, giving each other gifts in the spirit of generosity, and acting as befits a person who truly desires peace in the hopes that Hashirama, or his reincarnation, will arrive at their homes in order to give gifts of his own. Of course, in some legends, it's said that particularly naughty individuals will instead be visited by the fiendish half-corpse Madara, who gives the 'gift' of extreme violence and trauma. Speaking of which, let me double back to explain —"
"Mister Nagase, sir?" Tae finds it in herself to speak up before being subjected to whatever was going on with the explanation of Madara's not-death and subsequent sort-of-death for a second time. "It's not that I'm confused about any of that, as much as why we would celebrate it in a village Hashirama never visited or knew about."
Haru's brow furrows, and he looks over at the corner of the research center break room where a pile of ribbon-covered liquor bottles all sit underneath a slumping pine tree. There are a few other members of the Research Division making small talk, although as he now looks further it seems that everyone is confused and awkward about the circumstances.
"I mean, I don't believe in any of it myself, but I thought since Kei was so devoted to the holiday it would be the right thing to celebrate with him."
Kei stops drinking from his mug of hot sake to stare at Haru. "I don't celebrate this," he replies flatly.
"What? No. I was certain — hang on." Haru looks around the room. "Does anybody here actually celebrate Hashiramas?"
There is dead silence in response.
Kei drags his hand down his face. "Okay, well. How about we get rid of all these absurd decorations and costumes before the Director gets back and asks what the hell we're doing?"
There is a chorus of agreements on this. Haru is tasked with getting rid of the tree, and in the ensuing struggle with carrying and removing it, broke the bottle of sealing ink he'd gotten from the rest of the Chakra Studies team as a gift.
It was the worst Hashiramas anybody ever had in Hoshigakure.
It's still December so this is still marginally relevant. Shut up.
