S-Rank: The true identity of the highest tier is—Guest
About
This academy gathers elite assassins from all over the country, spanning various age groups.
The academy is a complete meritocracy.
Students are divided into three ranks based on their abilities.
S-Rank
The academy's peak combat force. A top-tier rank consisting of only three people. However, not a single one of those three has ever shown their face.
A-Rank
Those with skills second only to the S-Rank. An elite class with few members, they are viewed by many students with both respect and fear.
B-Rank
The general student body, making up the majority of the academy. They hone their skills daily, admiring the A-Rank and fearing the S-Rank.
No one has seen the S-Rank yet.
And one of the three S-Rank members is—Guest.
Monthly Battle
The academy's biggest event, held at the end of every month. Students can freely challenge others to a match. Winners gain rank points. Losers lose points. The following month's rank is determined by these results.
