Blade: Hi is pronounced like the male pronoun he. The kanji 秘 (hi) is short for 秘密 (himitsu), which is Japanese for the word "secret," in essence giving this Weapon Skill the name "Secret Blade."
Hi is also the one word for fire in Japanese, though the Kanji is different. This is likely the reason behind the fire animation.
