Article I - Peace
SOS団 and Tetris agree to remain respectful and polite to each other in all channels of communication, public or private. They also resolve to seek diplomatic means to any possible conflicts they may have. Both alliances should look out for each others well-being. As a consequence of their mutual friendship, both parties agree not to attack each other for any reason. In the event of a treaty conflict that would draw the two into war with each other, this article will take precedence.

Article II - Intelligence
Should either party receive information that pertains to the safety or well-being of the other signatory, they will seek to make it known to that signatory. Also, if either signatory has any reason to believe a security breach exists in the other alliance they are to present this concern and any evidence to their other signatory. Additionally, both parties agree not to commit espionage against each other.

Article III - Aid
Should a signatory request aid of any sort, be it military, financial, or diplomatic, from the other alliance, they are encouraged (though not required) to provide said aid as able.

Article IV - Optional Defence
Should a signatory come under the attack of a third party, the other signatory may offer military support to the attacked signatory, however this is not mandatory.

In the unlikely event either signatory wishes to cancel this agreement, they are to give 24 hours' notice to the other party with reasons through private channels. This treaty will remain in effect throughout that time period.
