The next day was Saturday. It was a holiday, but Tetsuya wasn't at home. He had promised Marin that he would accompany her to a cosplay event, so he quickly showered and got dressed.
He also opened the group chat, said good morning, chatted briefly, and did his daily login to earn 25 points.
"..."
Closing the group chat, Tetsuya immediately left the house. He didn't forget to lock the door and hurried off to the cosplay event location that Marin had mentioned the night before.
...
At the cosplay convention, Tetsuya saw large crowds there, most of them cosplayers. Actually, the otaku culture here was different from Tetsuya's previous world, no Naruto, Dragon Ball, or One Piece. All the anime and manga in this crossover world were completely new ones that Tetsuya had never seen before.
"Tetsuya-kun! Over here!"
In one corner, Marin called out to Tetsuya while waving her hand.
Right now, Marin was wearing a gothic-style maid outfit dominated by black, with frills on the upper arms and other decorations like lace, ribbons, and ornamental details. She had shoulder-length purple wig and purple contact lenses.
She was also wearing false eyelashes, a black hat with lace and three artificial roses on top, a three-layered skirt with the inner layer black, giving the skirt a flared impression.
The dress had a low-cut neckline top, with ribbon and lace accents sewn onto it. For accessories, Marin wore a white apron over the black skirt, with lace and ruffles around it.
She wore black rose-embroidered stockings. There was also tulle and a garter belt. The stockings were connected to her underwear with two straps on each leg. She wore black platform high heels.
"Marin?" Tetsuya called out, mesmerized.
Marin laughed and spun around once, causing her skirt to flare out as she smiled. "Ehehe~ What do you think, Tetsuya-kun?"
"Stunning. Marin cosplaying as Shizuku-tan is absolutely beautiful," Tetsuya smiled and complimented her.
Marin's appearance was impressive; she drew everyone's attention, especially the guys around them. If Tetsuya wasn't there, they would definitely have approached her. In fact, some had already tried, but Marin politely turned them down.
"Oh! Tetsuya-kun knows Shizuku-tan too?!"
Tetsuya coughed awkwardly and nodded. "A little... Anyway, what are we going to do here?"
Shizuku-tan, or Shizuku Kuroe, was a character from the video game series Saint ♡ Slippery's Academy for Girls - The Young Ladies of the Humiliation Club: Debauched Miracle Life 2.
It was an eroge. An adult game! Hentai!
Talking about that right now didn't feel appropriate.
"Hehehe, of course Tetsuya-kun has to accompany Shizuku-tan at this cosplay event!" Marin covered her mouth and laughed, then boldly stepped closer and hugged Tetsuya's arm.
Tetsuya enjoyed the sensation. Even though Marin was wearing breast pads to make her chest larger and better match the character she was cosplaying, Tetsuya could still feel the softness of her breasts.
It felt nice, though not as big as Saeko's.
"Sure."
Tetsuya then accompanied Marin around the crowded and bustling event. The otaku smell was strong in every corner, with cosplayers and spectators passing by.
There were also many booths selling light novels, manga, doujinshi (adult manga), and other otaku accessories. Marin bought a lot of anime merchandise, and she even dragged Tetsuya to buy a doujinshi that left him staring speechlessly.
Wasn't this girl embarrassed?
No. If it were anyone else, Marin would definitely be shy and wouldn't dare invite them to a place like this, let alone buy doujinshi together? That would be social suicide!
But since it was Tetsuya-kun, it was fine. Tetsuya had long known about Marin's otaku hobbies, especially the erotic (adult) ones, so she invited him to this cosplay convention and bought doujinshi with him without any shame.
Some people also wanted photos with Marin cosplaying as Shizuku-tan. The cheerful and kind-hearted Marin naturally agreed, but on the condition that they couldn't upload them to any social media.
There was a stage for karaoke, singing songs from famous anime or games. A large screen displayed the lyrics, with speakers on both sides of the stage.
The event lasted a long time, continuing into the afternoon.
The convention center was starting to empty out, but Marin tugged on Tetsuya's sleeve and whispered shyly, "Tetsuya-kun, actually... there's one more thing I want to show you?"
Tetsuya blinked and turned to her, seeing her flushed expression, and asked, "What is it?"
...
Marin took him to a hotel. After checking in, even though high schoolers weren't supposed to be allowed, Tetsuya's mature appearance that didn't look like a student's made the receptionist not suspicious enough to check his ID.
Now, the two of them rode the elevator in silence, with Marin fidgeting with her fingers shyly.
Once they reached the desired floor and entered the room, Marin locked the door and said to Tetsuya, "H-How about you shower first?"
"Mhm," Tetsuya nodded and went into the bathroom.
After Tetsuya showered, it was Marin's turn. Now Tetsuya waited for her while replying to messages on his phone and chatting with some women in the group chat.
Click.
The bathroom door opened, and Tetsuya saw Marin wearing a maroon red wig with twin tails and bangs hanging down to her shoulders, the back hair braided and tied with a fluffy black hair tie that had horns.
She also wore detachable pointed ears. The top part of her outfit consisted of a long-sleeved black top with a white lace collar and an extended white buttoned collar downward along with a white ribbon.
The sleeves were loose and cut off by white frilled cuffs. The bottom consisted only of underwear, and the outfit was completed with demon wings and a tail ending in a spade. For this cosplay, her nail polish had changed from shiny pink to black, and she wore olive green contact lenses.
Tetsuya's eyes lit up as he stared at Marin with intense interest, making her extremely embarrassed.
"Marin? No, Liz-kyun?"
Tetsuya hadn't expected Marin to have brought another costume all this time!
"Y-Yeah, Tetsuya-kun. What do you think?" Marin was very shy; compared to Shizuku-tan, this costume showed a lot more skin.
Tetsuya gave a thumbs up and said, "Beautiful! Sexy! Marin is so captivating! She has an irresistible succubus charm!"
"O-Ooh..." Marin blushed deeply, quickly composing herself and putting on a reserved smile. "Then I hope Tetsuya-kun is ready for what's next."
She stepped forward, pushed Tetsuya onto the bed, and straddled him. Looking at his handsome face beneath her, Marin felt an overwhelming urge.
She ran her hands along Tetsuya's abs, ending at his firm, broad chest, then teased, "Tetsuya-kun, am I... beautiful?"
Hiss!
Tetsuya felt the sensation of Marin's soft fingers on his chest. He nodded and said, "Very beautiful."
"Are you in love with me?" Marin's smile widened; she even moved her hand lower on his chest until...
Tetsuya blinked. He was a bit surprised that Marin would be this aggressive.
"Yes, I've been in love with Marin for a long time. Not only is she incredibly beautiful, she's also kind-hearted, cheerful, bright, and very..."
"Very?" Marin raised an eyebrow and asked, her cheeks red like tomatoes as she moved her hand even lower.
"Very sexy." Tetsuya smiled.
Marin's hand reached his crotch. She was extremely embarrassed by Tetsuya's words but also happy inside. Shyly and nervously pressing against his groin, Marin looked up at his face and smiled teasingly.
"Then prove it."
Without another word, Marin kissed his lips. Tetsuya was surprised again, but he didn't turn away and hugged her waist. They kissed intensely, even wrestling tongues and exchanging saliva.
Tetsuya groped every part of Marin's body in her Liz-kyun costume, feeling her smooth skin under his palms, and flipped their positions.
They broke the kiss, and Marin gazed up at Tetsuya with hazy eyes. "Tetsuya-kun, I love you."
Tetsuya smiled and kissed her again. They stripped off their clothes and were soon naked, as Tetsuya quickly pinned Marin beneath him.
