[Blue Lock] Nagi Seishiro Doesn't Want to Be Your Sibling

Title:

A childhood friend who's incredibly popular but also extremely possessive of you

A cosplayer girlfriend who secretly sneaks in and posts photos of you together online

A tsundere little sister who loves to bicker but depends on you completely

How do you choose?

Otaku guys online have been fighting over this question for years, with the three sides locked in a bitter debate. Then Nagi Seishiro appeared and ended the faction war single-handedly, proving to everyone that there was no need to choose. Isn't it obvious that you get the whole package at the start? It's that simple.

Everyone gangs up on him and leaves comments like, "I'll give you five yuan if you let me live your life for a day."

But only Nagi Seishiro knows the truth:

A childhood friend who acts cold in public but secretly wants you all to herself

A cosplayer girlfriend who works hard to earn enough money to make you so dependent on her that you can't live without her

A sensitive little sister who likes playing at being siblings, restrains her feelings for you, but is intensely obsessive underneath

They have 100% affection for each other from the start, and the two of them engage in a romantic push-and-pull comedy of everyday life. Pure romance, one-on-one. All other pairings are platonic.

"Having romantic feelings for my brother is absolutely, absolutely not normal!!"

Reo hesitates, then says: "...Have you ever considered that Nagi has been manipulating you this whole time?"

Third-person otome romance. Everyone likes the little sister.

Reo is the leader of the fake-sibling ship and gets tons of scenes. Chigiri is her bestie, and Anri is her life mentor.

Slow burn. The first dozen or so chapters are just me getting back into writing and quickly moving the plot along. I'll do a major revision after it's complete. The obsessive stuff is pretty mild and starts showing around chapter thirty.

The little sister is a seasoned otaku and professional cosplayer. Includes small amounts of Attack on Titan, Oshi no Ko, Madoka Magica, Jujutsu Kaisen, Demon Slayer, Bungo Stray Dogs, Naruto, That Time I Got Reincarnated as a Slime, Violet Evergarden, and My Dress-Up Darling.

No fanservice scenes, but there will be pandering to female fans.

Everything in the story about Japanese otaku culture is made up, since things are strict in Japan and copyright is hard to navigate. Feel free to substitute domestic versions, but please don't treat it as reality.

The jokes in the story's comment section all come from the internet. Please contact me if you want them removed.

Nagi's parents are an author invention. If Kaneshiro releases a flashback to Nagi's childhood, it won't affect the story.

Out-of-character warning. The highly aggressive, highly defensive Miffy bunny is dedicated to never blushing at cheesy pickup lines.

At its core, this is a sweet, brainless story with no logic, packed with all the otaku preferences that satisfy the author. I really, really need comments. Getting them would make me so happy and give me more motivation! [Very loudly: Please like me!]

If you like twisted love triangles, I have a short otome story next door. [Doge]
