(/Beautiful Boy/) To qualify, the title has to be filled with beautiful,
young boys (often with long, flowing hair) no older than high school aged.
Inuyasha and
Tenkuu no Escaflowne have both been marked as bishounen.
The nature of a story line are often defined by both the age and issues that the main character has to confront. A student in college would approach a situation very differently than someone in middle-school. This tag is intended suggest that the story is more mature (or perhaps less hormonally driven and spastic) in its nature. Aa! Megami-sama! OVA and Ai Yori Aoshi are both very good examples as to the fun adventures of a college-aged students.
