Can Kato the Arm target himself with his ability?

Ruling: Kato the Arm cannot target himself with his ability. He is expected to receive Day 0 errata to clarify that he must target "another friendly unit."

Nuances:

• As originally written, the card text would technically allow self-targeting, but this is considered unintended
• The errata has not been officially published yet but is planned for Day 0
