Ghost Trick and Phoenix Wright cross over! ... in these sketches by Shu Takumi, creator of both series. Capcom shared a series of Ghost Trick-related drawings made by the producer, featuring Sissel as a shadow and a Christmas tree, as well as various slices of (after-) life from the other characters.
The one here even features a bonus literary reference. The caption above is a quote from a haiku by Matsuo Basho, which translates to something like "I wonder how my neighbor lives?" And now that we've taken a brief detour into seventeenth-century Japanese poetry, you can find a video of Takumi drawing after the break.
