There are four Chinese games in Bi Constellation, each with only three characters.

There are only three strategies. In summer, three groups of animals can also take the lead (provided that Minister Catalpa and Minister Miki take the lead). Silver cherry Shiro can be introduced in winter (provided that the president is a mother and introduces wings)

After that, add two more raiders in spring.

Summer is still an animal trio.

Nothing increases in autumn.

Ophiuchus can be introduced into Kagurazaka Shiki in winter.
