[razorshaleh]

There will definitely be a new manga sequel later

 

[Shidqiramadhan47]

Onii-chan know the basics huh...

 

[xanon]

More likely, Aki will be a gyaru who's kind to nii-san.

There will definitely be a new manga sequel later

We do see an older version of her in one of the previous chapters, I believe.

 

[BanzaiYuri]

And thus a manga heroine was born, except the otaku will crush for her and she'll remain dedicated to nii-nii until Ch 200 where the axe demands progress XD

 

[Kaito57]

Big Bro planting the seeds for a Brighter Future...

 

[bigtiddyoneesan]

she'll grow into it

 

[Agent_Seagull]

"Be a gyaru who is kind to otaku"...
