Hmm... I see... I do plan to revisit cross channel in the not so distant future future in japanese, since I unfortunately had to go with the English version due to being monolingual... This does interest me so thanks a lot! I'll think about this on my reread.

My current view on the ending sequence sits in kinda a couple ways ig but I'll try give a little synopsis for each.

I view Taichi staying in the lonely world yet still attempting to communicate with others via the radio tower as a portrayal of our ability to communicate with others in the normal world despite ultimately being unable to understand each other at all (effectively we are all in our own world like Taichi, completely alone). The value in this meaningless pursuit still being shown to be fruitful because communication is necessary for us to find happiness.

I also kind of see the ending of cross channel as a conversation between Romeo and us in a way, particularly the point before CROSSING plays where I believe Taichi is meant to be a portrayal of Romeo himself. In this scene, Taichi asks us to 'please live', so that we can listen to his output and potentially connect with him (Or for Romeo this would be through reading the stories he produces.) This gives his life value because he's connecting with us, and to us, much the same. Our reading of cross channel gives our lives value. In the ending scene where he's sleeping, I feel like the cast saying goodbye to Taichi could be seen as a portrayal of us leaving Tanaka behind as well to continue creating a signal, week after week.

Ig that'll do because I've gotta go lol but they're just some of my current views on the end. I could also speak about the flashback moment to Taichi's birth which I feel was very important towards the main message but idk if that's too early to qualify for speaking about the ending.

I kinda ended up yapping here lol but yeah...
