Five heroes and one shadow

Shiva, Luna, Mr. Silver, Lisa, Lily, and Albert were at a meeting of the guardians and were figuring out how to deal with the shadow ones who killed half of humanity

Shiva: Let me attack them and kill them all at once? After all, I am stronger than all of you!

Mr. Silver: Shivu, they're stronger even if we all team up! So even you alone can't handle it...

Lisa: That's right...

Albert was just a guard who always followed Shiva as a "bodyguard," but he was hiding something... He was hiding the fact that he was a shadow, but no one even suspected it! But Lisa noticed it earlier, but didn't say anything because she doubted it*
