  It exploded right in front of his face.

  “Um...” Aiko stared in disbelief.

  The man spun around clutching at his eyes.

  “See? It doesn’t matter how big you are! No one can withstand an explosion right to the face!”

  “I guess not, but... What did you do?”

  “It’s a battery bomb! A homemade bomb made from a battery.”

  “Um... you walk around with that?” Aiko said. Everything about it was unbelievable. A bomb? There was a high school girl, standing in front of her, who walked around with homemade bombs?

  “For self-defense!”

  Suddenly, Aiko thought back to the dangerous objects she’d seen inside Yuichi’s pen case and bag. Mutsuko had picked them out, so naturally, she had some of her own.

  “And now, the finish!” Mutsuko drew something from her pocket. Aiko’s jaw dropped. It looked like a gun.

  She pointed it at the man and pulled the trigger. Something like a spring shot out of it, stuck in the man and caused his body to jolt. Then he fell over, limp.

  “Is that... a pistol?” Aiko asked timidly.

  Natsuki had had a gun, and Mutsuko had this thing. She was starting to fear for the future of Japan.

  “It’s a taser! I made this one, too. They’re illegal in Japan, so I keep it secret! It’s a type of stun gun, you know what that is?”

  The bombs were probably illegal, too, but Aiko decided not to bring that up. “It’s for self-defense, right? It electrocutes people?”

  “Yes! It shoots out electrodes, so you can use it even at long range! Taser is the name of a company that makes them. The electric shock locks up the muscles and incapacitates the target. But it only has an effect while the electricity is running, so it’s relatively harmless as weapons go! Stun guns themselves aren’t illegal, but ones with a firing mechanism are!”

  Aiko listened as Mutsuko joyfully went on and on about tasers.

  “Um... He’s unconscious, right?” The flow of electricity seemed to have stopped, but he still wasn’t budging. Aiko began to wonder just how “harmless” these things really were.

  “I guess maybe it’s not good to turn up the voltage all the way!” Mutsuko said offhandedly, deflecting the question.

  It was easy to imagine how increasing the voltage would increase the danger. Aiko felt her understanding of these siblings slipping away more and more.

  “Whew... You think it’s over? There’s no one else left?” From his spot on the floor, Yuichi let out a sigh of relief and looked around.

  Aiko did the same. Natsuki didn’t appear to have any more friends.

  “I think it’s over. Well then, Yu, we’ll get going the minute you’re mobile again!” Even with the battle over, Mutsuko was still in her own little bubble. Aiko almost admired the way she let it all just roll off her back.

  “Huh? What do we do with these two?”

  “They won’t be up for a while. So we can probably just leave a note or something.” With that, Mutsuko walked up to the unconscious Natsuki.

  She made a few furtive, secret motions, apparently writing something.

  After a while, Mutsuko returned and declared, “Okay, let’s go home!”

  Epilogue: Is This How a Harem Starts?

  The day after his death match with Natsuki, Yuichi returned to school. He was on his guard.

  They’d left the unconscious Natsuki on the floor and returned home. What would she do after she woke up?

  Mutsuko seemed to have had some thoughts about it, but she had yet to share them with Yuichi.

  Maybe she hadn’t changed her mind about slaughtering everyone. Maybe she’d start attacking people indiscriminately. If that happened, he’d need to stop her, whatever the cost.

  Fortunately, a full night’s sleep had let him recover from the furukami, and he was feeling ready. He could fight Natsuki again if he had to.

  Nothing happened on the way to school, or as he arrived at the school gate. Everything seemed normal.

  With his guard still up, Yuichi headed for his classroom. He opened the door with trepidation.

  The first thing he saw were the words “Jack the Ripper.” Natsuki Takeuchi was there.

  She was at her seat, facing forward with an sour look on her face. There was a large band-aid over her nose, and a patch over her right eye, and her entire face was swollen. It was rather painful to see her like that, sitting in the middle of the brightly-lit classroom. Even though it was the result of their fight, Yuichi felt a little guilty.

  Yuichi watched Natsuki, not knowing what to do. But he couldn’t stay there forever.

  “Morning,” he said, awkwardly. It was hard to talk naturally on the morning after you had pummeled each other.

  “M-Morning.” Natsuki made eye contact for an instant, then immediately looked away.

  Yeah, it would be awkward, huh? Yuichi thought, letting it go as he went to take his seat.

  “Ace Striker.”

  That was fast! He bounced back already?

  Shota had gotten there ahead of him, the “Ace Striker” title back over his head.

  “Congratulations.” Yuichi said offhandedly.

  “Huh? For what?”

  “No reason,” Yuichi smiled. “I just wish more people could be like you.”

  “Orihara! The last chapter of Demon King was really great!” Mutsuko exclaimed.

  “R-Really?”

  “Yeah! The way General Belnort’s Colossus crushed and kicked around the hero’s army as it advanced was really exhilarating!”

  “Th-Thank you...” Kanako responded shyly.

  What the heck? Colossus? Yuichi thought.

  Class was over for the day. Yuichi was dangling from the bouldering protrusions on the ceiling of the survival club, listening in to the conversation in bafflement.

  He’d decided to try out the rocks on the wall, climbed until he reached the ceiling, and then kept going. Eventually, he’d reached the middle.

  He looked down at the club room from his vantage point.

  Below him were his sister, “Big Sister,” “Isekai Fanatic” Kanako, and “Love Interest” Aiko. Mutsuko was talking to Kanako about her novel.

  “What’s gonna happen next? Wait, no, don’t tell me! I can’t wait to read it for myself!” she cried.

  “All I’ll say is that the last of the twelve Hell Kings is going to make his appearance.”

  “The full set! But won’t that be overwhelming when all the human side has is the hero?”

  “Don’t worry about that. The hero’s side is about to pick up a powerful ally.”

  “Oh, sorry. I guess I made you tell me...”

  “It’s okay. You’re the only person who really enjoys it anyway,” Kanako said, a little sadly.

  Yuichi felt guilty. He still hadn’t read Kanako’s novel. Judging by the way she acted, it didn’t seem very popular.

  “I think it’s amazing that you’re writing a novel, Orihara. I hope you’ll let me read it!” Aiko responded with enthusiasm. “By the way, what’s the title? What’s it about?” It seemed Aiko had been listening without knowing what they were talking about.

  “Well, it’s called My Demon Lord is Too Cute to Kill and Now the World is in Danger!, and...”

  It seemed like Kanako would be talking for a while. Aiko listened with a somewhat dubious expression. She had asked, after all, and Kanako was her senior, so she couldn’t beg off now.

  A certain “Otaku Haiku” came to Yuichi’s mind. “I didn’t ask that. Cut back on the detail there. Really, knock it off.”

  But it sure is peaceful...

  Natsuki hadn’t started any more trouble. She had just been acting normal in class as far as he could see, so they were probably out of the woods.

  Yuichi released the handholds, landed on the floor, and took a seat across from Aiko and the others.

  Aiko looked at Yuichi as if pleading for help.

  Yuichi refused to make eye contact. In Demon King-related matter
s, she was on her own.

  “Hey, where are the other club members, anyway?” Yuichi shrugged off Aiko’s glare to ask a somewhat overdue question. The current attendees were the same people who had been there yesterday. He was starting to wonder if other members even existed.

  “Well, participation is up to the individual. I’m sure they’ll stop by if they feel up to it,” Mutsuko said.

  “How many more are there?” Yuichi asked.

  “Three more. Maybe four?”

  “Why aren’t you sure? You should at least know how many people are in your club.”

  “That’s not what I mean... Oh, here’s one now.” The club room door opened. Had another club member showed up? Yuichi looked over to see.

  “Jack the Ripper.” It was Natsuki Takeuchi. The swelling in her face had gone down, and she’d removed the band-aid and the eyepatch. She seemed to have some degree of healing factor, if not as good as a vampire’s.

  “Huh?” he asked.

  Natsuki barged into the room, walked up to Mutsuko, and handed her a paper.

  Yuichi snuck a peek at it. It was a club membership submission form.

  “Huh?!”

  “Oh, I left this with her, along with the note yesterday!”

  “Hang on! Takeuchi? What are you doing here?!”

  “What do you think? Club activities.” She tilted her head at him. There was none of her icy manner from before. She was acting completely normal. “That is, I... I’m full, so...” Natsuki murmured, averting her eyes from Yuichi.

  “I don’t get it... just what did you put in that note, Sis?” Yuichi demanded.

  “Well, watching you yesterday, I started thinking. Takeuchi’s killing urge seems sort of like a sexual urge! So maybe she can divert it just by keeping her body moving! She looked really satisfied after you knocked her around and beat her unconscious. So I thought, maybe she doesn’t have to kill people, she just needs to spar with you! So I put that in the note.”

  What the hell kind of logic is that?! Yuichi looked at Natsuki. Her face was bright red. She must have felt embarrassed.

  “Hey! Wait, please! Wh-What do you mean, sexual urge...?” Aiko’s face turned red and she stood up. There was a lot she looked like she wanted to say about that, but she couldn’t find the right words.

  Yuichi looked at Aiko, and had a completely unrelated realization. This club is full of girls! Am I the only guy? What about the other three club members?

  “I look forward to working with you, Yuichi Sakaki,” Natsuki smiled. Above her head appeared the words “Love Interest II.”

  “Why?! This makes no sense!” he cried out before his mind could protest.

  Her label had previously been a reflection of her bloodthirsty nature. Yuichi had no idea what was going on.

  “What’s wrong, Yu?” Mutsuko looked at Yuichi quizzically.

  “Huh? Oh, nothing...” he lied, taking his seat.

  If Mutsuko learned he’d just acquired another love interest, she would probably start pouting again. He checked just to be sure, but she was still “Big Sister.”

  Does that mean this one’s wrapped up, at least? He didn’t have to worry about serial killers coming after him anymore.

  There was that mysterious organization, Noro’s brother, and other unsettling things waiting in the wings, but Yuichi decided to be optimistic and cross those bridges when he came to them.

  His high school life had only just begun.
