tricks a dragon into biting his shard covered hand

With a roar, the ordinary boy mercilessly threw a punch with a right fist covered in skyblue fibers.
He sent it toward those crocodilian jaws that were too big to miss.
The jaws of course chomped down on his arm.
Unbelievable pain burst in his head like sparks.
But that bizarre right arm had never been simple flesh and blood.
And had anyone really thought he would not put together some kind of plan from the
moment the chandelier fell to when he got up and clenched his bloody fist here?
Dark red blood did not just spill from Kamijou Touma’s bitten-off arm.
“Gah!?”
It spilled from those jaws as well.
Blood other than Kamijou’s poured endlessly from between those brutal teeth.
Kamijou staggered woozily backwards with a cold sweat soaking him, but he had a thin
smile on his lips.
“How’s it taste, monster?”
He could not use Imagine Breaker.
But he still had to win at all costs.
He had to free those girls no matter what kind of cheap and underhanded methods it
required.
So.
“'How’s a fist full of crystal shards taste? Pant, pant. It’s too late to spit it out now. Your
throat and stomach must’ve been shredded!”
