Lazarus of Soul Society...

BLEACH episode 224, is certainly a shocker when Hinamori Momo suddenly appeared out of nowhere! She was in time to save Matsumoto Rangiku from Apache's lethal attack.

In order to save Rangiku, she 'masked' her reiatsu from being detected by the three fraccions... And then she launched a fire ball using her zanpaku-tou Tobiume....

Apache, one of three Halibel's fraccion...

Eat this you arrancar bitch!

Have no fear! Hinamori is here!

Look can really be deceiving! This is the face of 5th Division's Fuku-taichou...

Don't worry Rangiku, I'll be by your side...

She is also master ni Kidou... she can mix more than 2 kidous at the same time!

Those who are not really familiar with her is forgiven because she had disappeared from Bleach airtime for quite sometime.

The last time she appeared was during the Arrancar Arc. During that arc, she was seen talking with Hitsugaya through a video monitor. She wholeheartedly believed that Ichimaru Gin was the one who manipulated Aizen and that Aizen really was innocent. Then, realizing the grave situation, she was quickly made unconscious by Yamamoto and his lieutenant Choujirou Sasakibe. From the short conversation it was proven that Hinamori had not gotten over Aizen yet.

In this episode she suddenly appeared to aid the guild fighting the Espadas at the fake Karakura Town... She declared her self as Aizen-taichou's enemy without realizing the mentioning of the word 'taichou'. This means she still has hope that Aizen will someday repent and come back to soul society....
