I realize I haven't been giving the two new mods introduced in Taiko PSP DX much attention since the launch of the game, so I'm going to do it now!
Kimagure (Whimsical) and Detarame (Random) are rather similar to each other, as both of them change random notes throughout the song into red or blue. It's actually quite hard to tell the difference because they do almost the same thing, but Detarame is like a more extreme version of Kimagure, with even more messed up notes. The positions of the notes do not change, like in Akekobe (Reverse).
Comparison videos for the two, using the same song: Hatsune Miku no Gekishou, since it's the only one with high-quality videos of the two mods and is also one of the nuttiest challenges due to THOSE STREAMS
(Kimagure is regular Oni, while Detarame is Ura. The notecharts are different, but the streams are almost the same so comparisons can be made there. They're almost the same anyway. If anyone knows the real difference between the two, that would be great!)
