On this episode, Nya-tan attempts to make a trade deal with Inu-tan and Kii-tan for their seals. Meanwhile, Shima-tan worries about Nya-tan's well being and her involvement with Takeru.
Whoa, this episode surprisingly explained a lot about Nya-tan's true intentions and why she seems to be silly. Also it was cool to see Takeru reveal to have sort of attraction towards Nya-tan. Other than that, Kii-tan and Inu-tan making trouble on purpose with our main heroine was just hilarious. Now what's going to be the next problem for Nya-tan? Overall, a funny filler episode.
Conclusion: A funny filler episode.
