Everyone Summons: From the Start, I Summon Kadoya Saya

This is a terrifying world overrun by monsters, where 70% of humanity has been wiped out.

In this world, firearms have become a thing of the past. When they graduate from high school, everyone must undergo a summoning ritual to call forth powerful beings from other dimensions: **, elves, weirdos, spirits, and even characters from other dimensions!

Jiang Teng transmigrates into his own body just before graduation. At the summoning ceremony, he summons someone completely unexpected.

A girl with ** abilities, the younger sister of Tsukasa Kadoya: Sayo Kadoya!

After forming a life-link contract, Sayo gives Jiang Teng the belt her brother entrusted to her.

And that belt turns out to be the Dark Decade Driver!

Thus begins Jiang Teng's Kamen Rider legend!
