Tomoda Dekantea

The Tomoda Dekantea is a vehicle featured in Himouto! Umaru-chan. It is based off the Nissan Serena C26 in the anime and the AH20 Toyota Alphard in the manga.

Description
The Dekantea is first seen in Episode 12 of Season 1 of the anime and chapter 42 in the manga, in which Umaru sees a commercial for the Dekantea and asks Taihei to buy one. It appears to have a rear seat entertainment system, albeit only one located in the driver's headrest (which Umaru uses to find another Dekantea advertisement, while dreaming of her and Taihei in it). It also appears to have a hybrid version, similarly to both the Alphard and Serena, and many other Japanese domestic cars. Its price tag is 3 million yen in the anime (most likely for the hybrid version), and 2 million in the manga (which is ironic considering the Alphard is an expensive car, more or less than the Serena).

Trivia

 * Dekantea (でかんてあ) literally translates to "I do not care".
