Anime is categorized by audience and tone rather than strict content types. Here's a quick breakdown:

• Shonen – Targeted at young male viewers; action-packed and energetic (Naruto, Dragon Ball).
• Shoujo – Romance and friendship-focused stories for young women (Fruits Basket, Sailor Moon).
• Seinen – Mature themes, complex narratives, often darker tone (Tokyo Ghoul, Vinland Saga).
• Josei – Realistic romance and drama for adult women (Nana, Honey and Clover).
• Isekai – "Another world" adventures where characters are reborn or transported to fantasy realms (Re:Zero, That Time I Got Reincarnated as a Slime).

Pro Tip: Genre doesn't limit creativity — many shows blend elements from multiple categories.
