Fans reserving the Blu-ray volumes 1 and 2 of Though I Am an Inept Villainess can get a linked manufacturer bonus: an original art board by illustrator Yukiya.
The bonus is a colored original illustration showing Reirin and Keigetsu as a child, laughing together in a warm style. It is available while supplies last, so early reservations are encouraged. Details are on the official Blu-ray bonus page.
The bonus is linked to volumes 1 and 2 of the Blu-ray release, and the illustration was drawn for this offer.
AniHeat's take: Worth noting for fans who collect the Blu-ray set or follow Yukiya's work, since the bonus is tied to specific volumes and ends when stock runs out.
