Light Novel: Mahou Sensou

Mahou Sensou (魔法戦争 / Magical Warfare) is a Light Novel series by author Hisashi Suzuki with characters designed by Lunalia.

The story revolves around Takeshi Nanase, who - his rather dysfunctional family aside - is an Ordinary High-School Student. His life changes completely when a girl named Mui Aiba collapsed on his school ground. She turns out to be a magician from another world and she is involved in a conflict against a group known as Ghost Trailer.

A one-cour anime adaptation by Madhouse aired during winter of 2014.

Mahou Sensou provides examples of these tropes:

  • Academy of Adventure: Subaru Magical Academy. As you might have expected, our hero, his girlfriend and other friend transfer there.
  • Accidental Kiss: Mui and Takeshi received their first kiss from each other in this fashion. Kurumi is not pleased when she finds out.
  • Becoming the Mask: Isoshima's relationship with Takeshi started as just an act to drive off stalkers but by the series' beginning she's in love with him for real.
  • Breast Expansion: How Isoshima discovers that she is a magician; her first transformation was here.
  • Combat Clairvoyance: Takeshi's power is "Evasive Magic".
  • Easy Come, Easy Go: The only thing necessary to obtain magic for an adolescent is to come in direct contact with magic. The only thing necessary to lose magic is to use it directly aganist another magic user in the real world. Although it was heavily implied that should a magic-using adult lose their magic, it will be Lost Forever.
  • Gainax Ending: The anime ends with Takeshi and Gekkou getting caught in a massive magic explosion, and Takeshi apparently waking up at Subaru in 1998. Combined with a number of other mostly-incomprehensible plot twists, and a lack of resolution for the series' existing plot threads, it makes for a very confusing and unsatisfying ending.
  • Improvised Weapon: The only weapon Takeshi can find to fend off the attacking Ghost Trailer members is a broom. Averted in the anime as he has a shinai with him at that time.
  • Love Triangle: Both Kurumi and Mui have feelings for Takeshi. The pretend relationship between Kurumi and Takeshi adds a wrinkle.
  • Meet Cute: Takeshi and Mui's first meeting is him finding her passed out on school grounds.
  • Playing with Fire: Ida's power.
  • Skewed Priorities: In the first episode, Isoshima was more concerned with her pretend boyfriend calling a girl she didn't know by her first name than the muscle-bound lunatic with the massive sword attacking them.
  • Talking Is a Free Action: Mui gives a big info dump in the first episode while she's sitting down talking with Takeshi. The problem, they were being chased and the chasers don't catch up until she's finished.
  • Theme Naming: The major characters have kanji numerals in their names:
    • Nanase (七瀬) has 七 (seven).
    • Mui is written as 六 (six).
    • Isoshima (五十島) has 五 (five) and 十 (ten) (when put together as 五十, it's "fifty").
    • Kazumi (一三) has 一 (one) and 三 (three).
    • Tsuganashi is written as 十 (ten).
    • Shijou (四条) has 四 (four).
  • Touched by Vorlons: This is how all magicians gain magic; they came into contact with magic from another magician. Takeshi, Isoshima, Ida, Futaba and Gecko all get magical powers after being attacked or accidentally attacked by magicians.
  • What Happened to the Mouse?: Among other questions the anime leaves unanswered: what happened to Ida's sister, who was taken by Wizard Brace's secret service?
  • Whole Plot Reference:
    • A Big Bad who leads a faction full of magic-wielding supremacists with the goal of conquering non-magical people, then suddenly disappears for more than ten years, awaiting his revival? Sounds a lot like Lord Voldemort.
    • A subset of humanity with fantastic powers fearing persecution. One faction wants to live peacefully with norms, the other wishes to dominate them. Where have we heard this before?
