~Prologue~

"Happy Valentine's Day!" Ketsuno Ana wore pink kimono with red flowers embroidered on the bottom. She wore bright clothes to represent the beautiful day filled with love, and that pissed off a certain silver haired samurai.

"Oh, shut it!" Sakata Gintoki scratched his head nonchalantly and rolled his eyes. Even though Gintoki had a huge crush on the bubbly reporter, Valentine's Day always turned his mood sour. "No one gives a shit if it is Valentine's Day." Jealousy was fuming out of his eyes as Ketsuno cheerfully interviewed the passing couples on the streets. It wasn't just the couples that were making him envious, but it was the brown squared sweets that melted flowingly on his tongue that drove him crazy. "Man, I wish I can buy those chocolates for myself." He picked his nose and grumbled in annoyance. "Kagura, go buy chocolate for me!"

"No way, aru!" As if Gintoki wasn't a substitute father, she lazily stretched out on the couch.

"Why the hell do I keep you around then. You are supposed to be a good daughter and go do what I say-"

Before Gintoki could finish, a quick and powerful kick flew towards his stomach. The impact was devastatingly hard, and the pain could be seen as Gintoki curled up on the floor.

"Kagura-chan.." Shinpachi was wearing the apron he wore to do the chores around the house. "Please don't kill Gin-san…"

"He asked for it, aru." Kagura replied back in a deadpanned voice.

Despite the fact that Shinpachi was older, he did not have the physical or mental strength to control Kagura. He let out a sigh and sat down on the couch to watch the news.

Ketsuno Ana was now by the river bank, and she was still cheerful about Valentine's Day. "Well, citizens of Edo! I have some news today!" Her face continued to beam with a smile. "The scientists came back with the results that today will be the last day of earth's existence! In approximately twelve hours, the world will go boom!"

Shinpachi could not believe what she had just said. How could a news reporter tell the citizens this disastrous news twelve hours before the doom? Also, Ketsuno Ana was known for her dead-on future readings. What am I going to do…the earth is ending! Shinpachi frantically looked at his two companions. "Gin-san, Kagura-chan. What are we going to do?!"

"Eh?" Kagura sat up on the couch and shrugged. She seemed like she did not care.

However, the silver haired samurai began to freak out. "Wait. What? What?! The world is ending? My dear Ketsuno Ana reported this, so it must be true! Oh no, what am I going to do? Am I going to die lonely with these two idiots? Oh no…"

Shinpachi watched his samurai friend and gave up hope. "I might as well spend my last twelve hours with my sister…you guys are useless."

"Then I'm going to find Ketsuno Ana so we can have our last twelve hours!" The two of them ran out of the Yorozuya Office, and Kagura was left alone.

Last day…huh.

In the Shinsengumi compound…

On the other hand, when the news of Apocalypse was reported, it was rather calm. Except one certain Shinsengumi Commander.

"Noooooooooooo." The large man let out a cry at the news. "That means I only have twelve hours to spend time with my lovely Otae-chan!" Kondo Isao was taking this news very badly. "Twelve hours is not enough! I need every minute, no. Every second of my living existing with her! Wait for me, Otae-chan!" Before any other members of the Shinsengumi can stop their impulsive commander, he burst out the door.

"Man, Kondo-san ran out again." The Demonic Vice Commander let out a puff of smoke into the air and let out a sigh. "Well, that's that." He straightened his uniform and stood up.

"You don't believe this, Hijikata san?" Okita Sougo mockingly asked him a question. "Don't you want to spend your last day meaningful? Would you like me to kill you early so you don't have to experience the Apocalypse?"

"Sougo, don't joke around. Who believes in this crap." He glared down at his companion.

"Well, it's supposed to be the last twelve hours, Hijikata-san. Don't you have anything to do?"

"Of course not. Plus, I don't even believe this nonsense, so I am going to my room to rest." He headed out towards the door and stopped to speak again. "Sougo, don't you have someone to spend time with in this last twelve hours?" A sly smirk appeared across his face as he exited the room.

What the hell was he talking about?!
