Because Saki 5C is airborne on frame 1, it can be kara-cancelled into air specials such as j2A (Gae Assail). In this video, the string 5B 5C~j2A (kara-cancel) is repeated while in the Time Arcana's EF (50% speed boost).
5B is a low and +1 on block. j2A is an overhead and very advantageous on block. EF Blast and guard cancel DP should escape this pressure string, but it may be very difficult to escape otherwise.

Time Akane 20,000 dmg combo (Six Stars only) (by @nekoran69)
Time EF makes your character move at 150% speed. This allows some moves with narrow collision boxes (and/or vs characters with narrow collision boxes) to pass through the opponent and hit on the other side. We call this "guard bypass" as an in-joke.
