Rayze and Tadashi...

 The two cards he had put on hold cost 50,000 luck points each.

That's right, the two cards were the 'Item Identification Card (D)' and the 'Event Information Card'.

He felt a little hesitant, but in the end he chose the 'event information card'.

At first, he wanted to assess Dandite's ax to see how powerful it was and how it could be used.

However, the 'event information card' was much more essential.

Right now, the amount of information he knew was too little. He needed to know more, so he could plan to resist or defeat the main enemies around him.

Especially Rayze.

[Ding! Do you want to buy an 'event information card'?]

"Accept."

[Ding! You have paid 50,000 luck points, you have successfully purchased the 'event information card'.]

[Ding! Would you like to use the event information card right now?]

"Accept."

Right after that, countless images suddenly appeared in Hikaru's head, startling him.
