**Might Contain Spoilers**
Since I started to drown myself in the anime world once again, I found few series that actually make me think about more than what we see or read. Most of the series that I read or watched, gave lot of information within the first twenty or thirty chapters, or around the middle of the season. In fact, I only found one series that doesn’t give a lot of information about the motive of some of the characters or the reason explaining why some event happen or thing exist. This series is Seraph of the End (Owari no Serafu). Even after two seasons and 50 chapters we still doesn’t that is exactly the Seraph gene, how it came to exist or where the virus came from.
