It's a shame Shino became a comedy actor in 2010 Naruto: Shippudencompletely destroying the impressive image he had built before the timeskip. During this time, Shino demonstrated the powers of the chakra insects, although the nature of his techniques were quite scary.
It was hard to imagine that the bugs Shino relied on would come out of his body and feed on his chakra, forming a symbiotic relationship. This revelation sent shivers down one fan's spine and made it hard to empathize with him, even after his character was murdered Naruto: Shippuden.

The beauty of Future diary is based on the tantalizing premise that players of this twisted game keep a diary that can predict the future in interesting ways. The main character is given a plain diary that easily achieves this goal, while Yuno's diary embodies her psychotic personality by tracking Yukiteru's movements.
For the most part, Yuno acts as a secondary protagonist, helping her partner whenever possible, although her obsession reaches dangerous levels, forcing Yukiteru to avoid her crazy side as much as possible. She is one of the best and most iconic examples of the creepy Yandere character who commits some heinous acts to prove her love to the person she is obsessed with.
