Hifuki no Koduchi

is a technique used by Love Aikawa's Zanpakutō, Tengumaru.

Definition
Love swings Tengumaru up and it ignites itself in flames he then points it downwards and a huge fireball fires from the tip where upon making contact with the target the fire explodes outwards a great distance with the resulting blast being strong enough to cave in buildings near the center of impact. At the site of impact a huge column of burning flames forms further incinerating anything in the area.
