The event weapon is from Baki the Grappler manga/anime weapon of Kaoru Hanayama's back tattoo..

In year 1616, the wealthy Hanayama family was massacred by a group of bandits and rogue samurai. Only one child survived.

To save the child, a man hastily hid the child inside a temple bell. He carried the bell on his back and blocked all harm from reaching the child using his own body. After countless sword strikes, cuts and stabs, the bandits had to admit that they could not bring down the man and so they had to give up. They voiced their respect to the man before leaving.

The child, and therefore the Hanayama bloodline was saved that night.

It was said that the man died many moments ago, but he would not fall. He would not let harm come to the child even after his death. He was only a drifter, a gambler who was nobody and a stranger to the Hanayama family. No one knew him or where he came from. He had no name.

Earlier that evening he was offered food and shelter. For the Hanayama's generosity, the man decided to pay with his life. If the last child was killed, then the man would never have been able to repay the Hanayama. He paid using his own life for just one evening of hospitality.

Since then, the Hanayama has honored the man as a true noble and worshipped him as a deity. Every male descendant since then would have the man tattooed on their back. The tattoo is known as　侠客立ち, which roughly translates to "The noble's unbudging stand".
