About This Content

Calculator - Desktop Mate Widgets: Natsuki Karin DLC is now available!

Every time you press a calculator button, the voice synthesis software character Natsuki Karin speaks that number and strikes a pose. With voice lines newly recorded for Calculator - Desktop Mate Widgets, your everyday calculations become a little more special.

■ 4 Natsuki Karin-Themed Designs

Choose from four Natsuki Karin-themed designs — from an elegant soft purple palette to a cute paw-print design. Switch up your design to match your mood or the moment.

■ Performance Mode: Natsuki Karin Sings Along

Switch to Performance Mode and Natsuki Karin will sing along to every key you press. Hold "+" or "-" to shift notes by a semitone, and multi-key presses are supported too. With a little practice, you might be able to pull off a real performance!

■ SP Answer Actions

Certain calculation results trigger special reactions from Natsuki Karin. Try entering "7216" — something might just happen! See how many hidden reactions you can discover.

■ Save More with the Bundle

A bundle is available that lets you get both the Desktop Mate Natsuki Karin DLC and this DLC together. Even if you already own one of them, purchasing through the bundle page gets you a special price on the other.
