What does it mean that the group members have given me back the light?

"Light is the bond, and it will continue to be passed down."
Gu Nuo thought this sentence was cool, but he didn't want to become the light.
What's the point of becoming Light? Is it to endlessly fight off alien beasts? Or is it for some organization plotting to capture suitable candidates for human experiments?
So...who wants this thing!
[The strongest elbow striker: Holy crap! @Noah is still chasing me. After catching your light, I blew up a top-tier cursed spirit with one elbow strike?!]
[Want to drink Mei's juice: Thank you @Noah, you're still chasing me! With the light you lent me, I finally defeated the second personality within me!]
[Mitakihara Arms Queen: @Noah is still chasing me, the light works very well, Witch's Night has already exploded.]
Noah is still chasing me: ?
Is something that can be passed down so easily?
However, if it's been passed down, then so be it.
This was Haji's own choice, and hopefully it will bring its talent to a more useful place.
Gu Nuo breathed a sigh of relief with mixed feelings, but soon he took off running.
Because he saw that the Evolution Trusters, with even greater power, jumped out of the chat group and followed him closely.
Damn it! Noah is still chasing me!
