My Tsundere Sister v1.01 Patches Audio and Gallery — and Clears Up a Beauty Mark

YAMAYURI GAMES has released v1.01 of My Tsundere Sister, a post-launch patch that arrives with a handful of tangible fixes and one clarification that the studio clearly felt could not wait.

What changed

• CG Gallery: The title screen key visual has been added to the gallery.
• Audio: BGM and sound effect loudness have been adjusted so that, under default settings, background music sits in better balance with voice volume.
• Video: General video performance has been improved.
• Miscellaneous: The update note cites additional unspecified improvements.

The patch is available through Steam's automatic update system.

On the subject of the missing beauty mark

The studio also used the announcement to address player reports that a beauty mark on character Lumeng's chest disappears in her pajama sprite. After comparing the artwork, the development team concluded this is not a bug: the mark is beneath her clothing and fully covered in that variation. A proposed workaround — adding a dot at a higher position — was considered and rejected in what the studio describes as "the spirit of scientific rigor."

For players who found the audio mix uneven at launch or noticed the gallery felt incomplete, v1.01 is a direct response. The beauty mark question, meanwhile, is now officially closed.
