"This idea doesn't seem to have any problem, maybe it's worth a try."
After Kamiyagawa returned home from school, he didn't immediately log into Strange Tale World; instead, he sat at the desk fiddling with something.
On the table lay a Soulbreaking Iron Bullet and his usual incantation aid for summoning Yin Thunder, a "Thunderwoven Coin."
"I chose a 10-yen coin to summon Yin Thunder because the coin itself is made of conductive metal and it's quite small, making it suitable for Yin Thunder to gather and burst forth. Plus, it's easy to carry and to get a handful of them."
"But now it seems that an iron bullet has all the properties suitable for being an incantation aid, right?"
Kamiyagawa picked up the iron bullet with his hand and activated a Yang Thunder spell.
Crackle!
Eerie blue and bright arcs of electricity danced from his fingertips, attaching to the iron bullet.
He then checked the item's information through his phone.
