There was a particular cutscene which I found hilarious and adorable involving Tataru and boxes in 2.5 or 2.55. I wanted to go back and watch it, but it wasn't in the book found at the inns. I haven't looked to see if the other times Tataru went adventuring, but it made me wonder why it wasn't there.
We all need our dose of Tataru. Gimme it, Yoshida, please!
