Fuu Hououji - Season 1

Season 1

Fuu attended a private school for intellectually gifted children. She was on a school trip to Tokyo Tower when she saw an energetic girl enjoying the scenery through the telescope. This girl is Hikaru Shidou, though Fuu didn't know her. When she saw her running out of money to continue viewing, Fuu approached her and gave her spare tokens to continue the journey. Only moments after she left, she heard a voice calling her out as Magic Knight. In instant, along with Hikaru and another girl named Umi Ryuuzaki, Fuu was transported to Cephiro. Despite everyone else looking panicked, Fuu remained calm and was the one to initiate the three to introduce each other.

The girls met the Master Mage Clef shortly after and he told them the plight of Cephiro, starting from Princess Emeraude's imprisonment by High Priest Zagato. The only way for them to go home was to save Cephiro. Fuu decided to just "play along", unlike Hikaru who was more than willing to save Cephiro, or Umi who kept insisting to return back to Earth. Unfortunately, Zagato's minion Alcyone attacked them and the girls had to flee. She gave pursuit, but was eventually driven back by Hikaru's magic.

The girls were soon sent to Legendary Spring of Eterna by Presea to obtain the Legendary Minerals of Escudo. On the way, while traveling inside the Forest of Silence, they met a swordsman named Ferio whom Fuu eventually persuaded into their bodyguards. After this, the outcome differed between the anime and manga.

• In the anime, they stumbled upon a stone that turned nearby animals to monsters and also dragged humans that tried to attack it and turn them to stone. While Hikaru and Umi distracted the monsters, Fuu and Ferio were about to destroy to stone, but Ferio, being a close-ranged fighter, ended up being dragged to the stone. After urging Fuu to believe in herself, she took her bow and shot a sure shot to the stone, destroying it. After this battle, they managed to exit the Forest of Silence. Ferio gave the girls a certain box, in which he claimed that it may grant a wish to come true, and left. However, Fuu started to develop small feelings to him.

• In the manga, the encounter with the stone didn't happen. However, right after exiting the forest, Alcyone ambushed and wounded Umi from behind. While Hikaru fought a losing battle, Ferio became desperate and wanted to help, but Fuu stopped him, saying that it's Hikaru's fight. Eventually, Umi couldn't take it anymore and managed to acquire her magic and ultimately drove Alcyone away. Looking at Umi's wounds, Fuu also wished for magic and soon Clef gave it to her through telepathic link. With her spell, she healed Umi's wounds. Ferio also departed at that point, but not before he gave a ring to Fuu, causing her to blush heavily and even lost her sense of direction for a short moment.

The girls eventually obtained the mineral of Escudo and brought them back to Presea. In the anime, she's killed by Ascot's monsters while completing the weapons, but in the manga, the attack didn't exist. The girls now journeyed to revive the Rune-Gods. As they journeyed they grew into best friends.

In the anime only, the girls decided to use the box Ferio gave to them. It turned out to be a communicating device to Ferio himself, and while Hikaru and Umi's wishes were deemed to be "stupid and loud" by Ferio, he was stunned with Fuu's wish, who just wanted him to be safe. The girls later met Ferio again, secretly under the contract of Ascot to lure the girls to the desert. Although it looked like he would betray them, he ended up helping them. Unfortunately for him, Ascot caught him red-handed and used him as a hostage to lure the girls again. During the night, Fuu left her friends alone to save Ferio. They ended up helping each other to survive, and eventually after Ferio used himself as a bait to the monster, which was sensitive to sounds, using Hikaru and Umi's wishes recorded in his communicator, and told Fuu to run, she didn't run and resolved to fight. This results her sword to evolve and finished Ascot's monster in one blow. Afterwards, Ferio left again, but he would occasionally help the girls.

Fuu was the second to revive her Rune-God, Windam. The events differ greatly between the anime and manga.

• In the anime, the girls met Ferio again, this time taking care of a girl named Selena. Although he was just "taking care" of her, Fuu grew jealous on her and left with her hearts in doubt. Unfortunately for Ferio, these were all a trap set by Zagato's minion Innouva (an anime-only character). When Fuu confronted Windam, Innouva knocked Hikaru and Umi away and fought Fuu before revealing that he had Ferio as a hostage, and told her to choose between Ferio's life or Windam's power. After several thinking, eventually Fuu chose to save Ferio. This proved her heart's strength which Windam quickly acknowledged. He used his power to drive Innouva away, and eventually granted Fuu his powers, but would not be seen again until the last Rune-God is revived. In the end, Ferio was overcame with guilt and after a brief apologizing he left. But he later helped the girls to ultimately defeat Innouva through his communicator.

• In the manga, the dancer Caldina used her dance to brainwash Hikaru and Umi, and she had them fight Fuu in front of Windam. She tried her best not to injure her friends to the point that she developed a new spell to immobilize both of them. Caldina then manipulated Fuu with her dance, directing her to attack Hikaru and Umi. However, Fuu was merely "playing along" with Caldina's tricks and ended up blasting her with magic. Shortly after, Caldina repented her ways and walked away in a friendly note, and Windam also acknowledged Fuu's heart strength. This event also happened in the anime, but it has nothing to do with the test.

Eventually, the girls were able to revive all the Rune-Gods and defeated Zagato. However, this just incited the anger of Emeraude, who had fallen in love with Zagato. The Magic Knights were attacked, and after Emeraude told them the whole truth and the purpose of her summoning was to kill her, the girls had no choice but to kill her. Emeraude was at peace and the girls returned to their world. However, their hearts were filled with grief due to the shockingly sad event.
