I know like one thing thats in that trunk, is it like legal to see all the items in that trunk?

Yes it is legal, if you go to subetahq you can see All items in All the trunks

It's perfectly alright. SubetaHQ Lists all the items in the trunk, both currently available and retired. You can also find them in the Human avatar board.

Just making sure. Thanks guys!

EDIT: Wait! I tried to look it up on the Subeta HQ and they didnt show me what was in there!

click on the MCT you want to see then click on either male/Female items

they didnt show up. But I found them in a forum post.

They're definitely there. The MCT items are listed individually under each specific trunk, which is also split into the male set and the female set. The items themselves are listed just like any other wearable item. There's no rule that says you're not allowed to look them up!
