If you don't play LN you wont get it :/

I’ll let you off the hook of calling RK seven for relatable

He has multiple names I saw a few people call him "The Kid"

That’s actually his official name

I think Runaway Kid and Seven are better names ya know. More catchy than "The Kid"

RK became official after complete addition and everybody gets annoyed at the use of seven now

I like the name Seven and I like to be petty lol.
