Although Sareth felt awkward about this unfamiliar human world and found it difficult to integrate, he did not forget his missions.
He was actually a pretty smart child. When he found that his behavior was vastly different from that of the humans of this world, he tried his best to minimize his contact with humans and instead hid to observe quietly.
He found that humans would obtain information through some kind of paper called 'newspapers' with words printed on it. In addition, there was also a moving image called 'television'. These novel things gave him a sense of freshness, and he also found a way to complete his missions.
