I`ve looked into CH 3C routes at low meter. I hope this will be helpful.
terminology: 1 foot = 1 hakumen sole
0 magatama:
Midscreen/Back to corner:
(0) CH 3C, 3C (1795, 0.65)
(0) CH 3C, 2B > 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > j.C (2583, 1.16)
(0) CH 3C, 2B > 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > agito (2476, 0.05)
note: max range is that of after 3C hit at point-blank range; tough timing on carl.
(0) CH 3C, 2B > 5A(jc) > j.B > j.2A(jc) > j.2A > j.C (2482, 1.05)
(0) CH 3C, 2B > 5A(jc) > j.B > j.2A(jc) > j.B > j.2A > agito (2479, 0)
note: max range is 1 backdash from enemy, except for celica, makoto, terumi, rachel for +1 foot and taokaka for +2 feet.
Corner:
(0) CH 3C, 2B > 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > j.C > agito (2739, 0.16)
(0) CH 3C, 2B > 5A(jc) > j.B > j.2A(jc) > j.2A > j.C > agito (2658, 0.05)
note: range is bigger for 5A > 5B version.
1 magatama:
Midscreen/Back to corner:
(1) CH 3C, 2B > guren, 66 5A > 5B(jc) > j.B > j.2A(jc) > j.B > j.2A > agito (2734, 0.17)
(1) CH 3C, 2B > guren, 66 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > j.C (2736, 1.2)
(1) CH 3C, 2B > guren, 66 5B(jc) > j.B > j.2A(jc) > j.B > j.2A > agito (2868, 0.13)
(1) CH 3C, 2B > guren, 66 5B(jc) > j.B > j.2A(jc) > j.2A > j.C (2872, 1.17)
note: the most stable and easy combo.
(1) CH 3C, 2B > guren, 66 2C(jc) > j.B > j.2A(jc) > j.B > j.2A > agito (3128, 0.18)
(1) CH 3C, 2B > guren, 66 2C(jc) > j.B > j.2A(jc) > j.2A > j.C (3132, 1.24)
note: works only at point-blank range or back to corner. Doesn`t work on Tager and Litchi at point-blank range.
(1) CH 3C, 2B > guren, 66 6A > 6B, 5A > 5B(jc) > j.B > j.2A(jc) > j.B > j.2A > agito (3201, 0.56)
(1) CH 3C, 2B > guren, 66 6A > 6B, 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > j.C (3203, 1.56)
note: works only at point-blank range. Doesn`t work on Tager and Litchi.
(1) CH 3C, 2B > guren, IAD j.B > j.2A |> 5C > kishuu > 2C(jc) j.B > j.2A(jc) > j.2A > j.C (3610, 0.5)
note: timing differs between characters and depends on player position; do IAD just before wallbounce.
Corner/Near corner:
(1) CH 3C, 2B > guren, 2C(jc) > j.B > j.2A(jc) > j.2A > j.C (3132, 1.2)
(1) CH 3C, 2B > guren, 2C(jc) > j.B > j.2A(jc) > j.B > j.2A > agito (3128, 0.18)
(1) CH 3C, 2B > guren, 2C(jc) > j.B > j.2A(jc) > j.2A > j.C > agito (3325, 0.25)
note: enemy leaves corner at close range (character depended); timing might be tricky.
(1) CH 3C, 2B > guren, 6A > 6B, 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > j.C > agito (3321, 0.55)
(1) CH 3C, 2B > guren, 6C, 2C(jc) > j.2A(jc) > j.2A > j.C > agito (3740, 0.45)
(1) CH 3C, 2B > guren, 6C, 6A > 6B, 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > j.C > agito (3718, 0.8)
(1) CH 3C, 2B > guren, 44 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > j.C > agito (2828, 0.2)
note: most stable corner combo.
(1) CH 3C, 2B > 5A > 5B(jc) > j.2A > j.C > hotaru(jc) > falling j.C |> 5C > 6A > 6B (3149, 1.6)
note: works from 1 backdash range - 1 foot; delay jump a bit after hotaru.
Character specifics:
Azrael, Valkenhayn, Kagura, Amane, Mu-12 (Gang of Five) have guren "immunity" at close range.
Minimal distance for guren to connect:
Azrael - max distance possible; has full immunity in corner;
Valkenhayn - 1 backdash + 3 feet;
Kagura - 1 backdash + 2 feet;
Amane - 1 backdash + 1 foot; 1 backdash + 2 feet in corner;
Mu-12 - bit more than 1 backdash; 1 backdash + 1 foot in corner;
2 magatama:
Most combos here are very similar to 1 magatama versions, but they are much more forgiving in terms of execution and more stable.
Every combo with renka will work on GoF.
Midscreen/Back to corner:
You can use most combos from 1 magatama section replacing "2B > guren" with "2B > renka", but damage output will be lower. Use those combos on GoF members, and guren versions on the rest of the cast.
(2) CH 3C, 2B > renka, 66 2C(jc) > j.B > j.2A(jc) > j.B > j.2A > agito (2939, 0.05)
(2) CH 3C, 2B > renka, 66 2C(jc) > j.B > j.2A(jc) > j.2A > j.C (2942, 1.1)
note: works up to 1 backdash distance and back to corner.
(2) CH 3C, 2B > renka, 66 6A > 6B, 5A > 5B(jc) > j.B > j.2A(jc) > j.B > j.2A > agito (2981, 0.4)

note: works up to 1 backdash distance.
(2) CH 3C, 2B > guren, IAD j.B > j.2A |> 5C > kishuu > 2C(jc) j.B > j.2A(jc) > j.B > j.2A > agito (3608, 0.45)

Corner/Near corner:
(2) CH 3C, 2B > guren, 6C, 2C(jc) > j.C > hotaru > fall, then AD > j.2A > j.C > 5C > 6A > 6B (4768, 1.06)
note: possible really close to corner.
(2) CH 3C, renka, 6A > 6B, 5A > 5B(jc) > j.B > j.2A(jc) > j.2A > j.C > agito (3034, 0.24)
Character specifics:
CH 3C, 2B > renka doesn`t work on Noel.
