Hiragana is unambiguous. You can look up exactly what it is. When you look it up you get "Tessaiga", not "Tetsusaiga".
I'm as annoyed as you are if "Tetsusaiga" is a stupid mistake which The Rules are perpetuating, but I'm afraid your argument goes nowhere. There's an unambiguous transliteration from the English to the German alphabet, and yet the Germans persist in calling that big state on the west coast of the U.S. by their own name "Kalifornien". (This despite the fact that they have no problem spelling Oregon and Nevada "correctly".) Similarly, Americans insist on misspelling France's third-largest city as "Lyons", even though that they have no problem with "Paris".
