Night Wizard

Renji Hiiragi is one of a chosen group of mages known as the Night Wizards. Their job is to make sure that evil doesn't get into our world, keeping it hidden from the eyes of Muggles. This is all well and good, except Renji really doesn't want to do the whole "saving the world" thing, no matter how good he is at it. He has a reputation as "the Falling Man", and is constantly missing class. He wants to make sure that he actually shows up at school and gets work done, but his party's leader Anzelotte just keeps calling him away and not giving him any other choice in the matter.

One day, Renji is told that he will have to watch over New Transfer Student Eris Shiho. Eris is waiting for her birthday, at which point she'll finally meet the Mysterious Benefactor who's been aiding her since she was young. After getting dragged into the Astronomy Club, Eris finds herself joining Renji's party on a quest to recover the seven Jewels that her bracelet is tied to. At the same time, a dark mage -- Bell Zephyr -- begins to move.

The series aired in fall 2007.

Tropes in Night Wizard include: ""Please answer 'hai' or 'yes'.""
 * Back From the Dead:
 * Break the Cutie: Poor Eris. She learns that  She gets better though.
 * BFG: Akari's weapon of choice. She uses it as the "wizard's broom" too.
 * Later in episode 9, she got much bigger.
 * But Thou Must: Anzelotte pulls this on Renji regularly.
 * Catch Phrase: Nightmare says "Dream" all the time, but since he's Japanese, it's something like "Durimu".
 * Chekhov's Classroom: Science class saves the day as far as one of the Jewels is concerned.
 * Club President: The Astronomy Club, led by Kureha. It's really more of a convenient way to gather the Night Wizards in the school.
 * Emotionless Girl: Akari. Her face doesn't even change when she is angry.
 * Enemy Mine: Bell does end up joining with the heroes in the end, if only for one battle.
 * Evil Overlord: Bell Zephyr fits many of the standard Overlord tropes.
 * Gotta Catch Them All: The seven Jewels of Virtue, a group of Cosmic Keystones that are very, very important.
 * Hammerspace: Eris' Lunar Robe, that can be used to store weapons.
 * I Just Want to Be Normal: Renji's extreme desire to actually finish his education. He's smart enough to get it done, he just never gets a chance to actually be in school.
 * Instant Runes
 * Journey to The Center of The Mind: One episode takes place in Eris' dream world, and introduces Nightmare.
 * Miko: Kureha. This extends into her fighting style, where she uses a crossbow loaded with charms.
 * New Transfer Student: Eris
 * Noodle Incident: What is Hiiragi's secret Kureha keeps teasing him with?
 * Orphan's Plot Trinket: Eris' bracelet
 * Really Seven Hundred Years Old: Both Anzelotte and Bell are hundreds of years old, but look young and active.
 * Red Sky Take Warning: More like Red Moon Take Warning
 * The Reveal:
 * Sink or Swim Mentor: Anzelotte's catchphrase sums it up well enough. After she gives Renji the details of what he needs to do:

""Please answer 'yes' or 'okay'.""
 * Just to clarify "hai" means "yes" in Japanese.
 * The subs have her say:


 * Wake Up, Go to School, Save The World: Renji, although Anzelotte rarely lets him go to school
