Ash had a rather bad habit: when he felt a relationship becoming close (in his view), he enjoyed draping his arm around others.
Igula was very disdainful of this, but after slapping Ash's hand away a few times, he didn't bother anymore. When Ash draped an arm around the Swindler, it always gave the impression of two little cats; Ash was a tabby cat, and Igula was a ragdoll cat.
Harvey didn't mind, but on the contrary, Ash didn't quite dare to place an arm around his shoulders. When walking with Harvey, Ash felt like he was a husky resembling a wolf, but Harvey was truly a wolf resembling a husky.
Tamasi didn't mind either, but as his nickname suggested, when walking with him, Ash felt like a dove while Tamasi was a crow. Ash's outstretched hand was like the wings of a dove, never able to truly grasp the Black Crow.
At that time, he vaguely felt that Tamasi was a person not to be bound by emotions, like a bird in flight.
