The moment I read about this news, a huge smiled popped in my face. Seriously, if you like japanese TV shows, Domoto Kyoudai is one of the funniests, and aways has awesome guests.
I understood Tomomi will be part of the band, and will participate in the talk segment for the first airing, but will she be a regular on the talk segment, or she will be just like Shishido Kavka and the others, appearing only on the music performances?
I hope she will be a regular on the talk segment, too. This show is too awesome to leave Tomomi out of its main segment.
Just one thing, I'm not sure about this, but I hope Takamina is still a part of the show, too. She is the most active female member of Domoto Kyoudai ever, it would be a shame if she had to leave. Although, Tomo's "character" (the "dumb"* character that everyone makes fun of) would overlap with Takamina, so I think if Tomomi becomes a regular on the talk segment, probably she will replace Takamina. I would love to see how a "cool" character such as Mami or Rina would do in a TV show like this one, but oh well, it's already great to see a member of my favorite band as a regular member of my favorite TV show.
*No, I don't think Tomomi is really "dumb", it's just her character, someone that people tease during talk shows.
