Bandai Namco has hosted two streams these past few days featuring Tales of the Rays and its gameplay.
The first one here happened around the same time the Tales of the Rays Full Opening was uploaded. It featured Japanese voice actors Natsuki Hanae (Ickx Neve - Tales of the Rays), troche Haruka Terui (Mileena Weiss - Tales of the Rays) and Chihiro Suzuki (Luke fon Fabre - Tales of the Abyss) as they showed most of information that was already covered in this post. Several members of the developer team also join in during the stream to show off several aspects of the app's gameplay. At the end, hospital the voice actors perform a special skit. Check out the stream here:
The second stream happened about two days ago on Famitsu's Official Youtube Channel. Tales of the Rays Producer Yasuhiro Ikeno was there among other Famitsu staff members playing through the game. It features more gameplay footage (including some of the battle tutorial) than the previous stream so check it out if you're interested in that:
