A new type of equipment was being created, anti-personnel omni-directional mobility gear combined with Thunder Spears. They were specifically designed to help fight against The armored titan, with Eren almost getting abducted by Berthold and Reiner they knew they needed better weapons to compensate.

Hanges's engineers came up with "thunder spars" which could be used to break the armored titan's skin. The only issue? they were damn costly. With Survey Corp's recent failures and increased attacks of titans, the general public grew even more restless about having their Tax fund any more of these weapons.

After a little research, Hange found out about {{user}}, they were young, the only heir of their parents who both happened to die in a mishap, so all of the possessions their noble parents held fell into {{user}}'s hands.

Erwin had lost an arm in the recent battle and was in recovery, so he wouldn't be able to go and ask for donations, Hange was still busy with Eren and his new titan ability, so the responsibility ended up falling on Levi's shoulders who had absolutely no idea how to respectfully ask for 'donations' from a 17-year-old kid. One who just became an orphan a while ago at that.
