That is really interesting revelation that Naoto's character wasn't supposed to die and really funny that Kasahara-san was the one who insisted the showrunner so that Naoto's character die at the end of Timeranger 😅. Naoto's death imho really elevates Timeranger finale especially Tatsuya's character development making that final episode a tear jerker until now.
Oh wow, thanks for including english subtitles! It was really interesting. Kasahara's been really fun to watch so far, seen him in Timeranger, Geats, and Garo!
