It's Valentine's Day! Happy Valentine's Day everyone! For today's blog post, I will be talking about Tsunderplane from Undertale. Since it's a holiday, I decided to talk about something a bit less than usual. Tsunderes are also a very well-known anime trope, so I figured it would be a good subject for a Valentine's Day post. Now that that's out of the way, let's get on with the post! Tsunderplane is a character from the game Undertale, and it is one of the monsters you can encounter in Hotland. It can sometimes be encountered with Vulkin as well, and Tsunderplane obviously has a very tsundere-based personality. It often says things like "It's not like I like you", and it will occasionally call the protagonist an idiot. Tsunderplane seems to like the protagonist too, since it acts very embarrassed or defensive when the protagonist is talking/flirting with it. As always, I will be including a picture of Tsunderplane below so you guys can see what it looks like. Enjoy!
