Here's the information about the new MC (shiniki no campionees)
Name: Rokuhara ren
Age:19~20
Personality:Extremely easy going, can get along with anyone including gods(Some gods can't sense a killing intent from him.) and has a lot of experience with women. (Wiki translation is a bit muddy, so there might be some slight inaccuracies)
Occupation:College students, God Killer(This world's campione)
Fightning style: Boxing
List of the gods he'd slain: Nemesis and Nike(All goddesses, see the pattern here?)
Herem member: Toba Riona, Stella(Aphrodite), Cassandra

Authority lists:

1. Nemesis's cause and consequence(Nemesis):
1.1 This authority allows him to reflect all kind of attacks(enemy's weapons, beast nails and fangs and god's authorities). It's a causality manipulation authority.
1.2 To reflect enemy's attack user has to see the attack till the last minute. (It can't be use when unconscious)
1.3 When activated the user gained visual acuity that could catch up with godspeed(150 KM/S)
1.4 The user can stockpile the attack in a form of arrow. As a goddess of justice, the more sins opponent has committed, the more powerful the attack will be.
1.5 This authority isn't reflecting attack normally, but replaying it back to the opponent(It has an element of time manipulation)
1.6 It can be applied to object that isn't user.
1.7 It can punish people according to the sins they've committed(This part is extremely messed up in the wiki, so take it with a grain of salt.)
1.8 It grants him godspeed. Normally, it's a little bit faster than normal human, when fully activate Ren will gain speed and reflex of godspeed. It's fast enough to evade a lightning strike and cover a distance of 5 km or more within a few seconds. User can move freely even underwater. It is a form of time manipulation under a principle of "I'm moving to the future a little bit faster". This power can't be used by two individuals at once, since it will cause the authority to go haywire. A burden from using godspeed to the body is extremely small.
1.9 It can create an avatar of Nemesis as an illusion.
1.10 If user put his life on the line the power will increase dramatically which is enough to kill god several times over.

There's are drawbacks that when use heart and lungs function will slowly deteriorate. If the pain passes the upper limit the user will die. It also hard to instantly reflect the large scale attack, and country busting will have a very high possibility of failure.

2.Friend ring(Aphrodite):

2.1 It allows him to summon a god that he's friendly with.
2.2 It has a very high MP consumption.

3.Wing contract(Nike):

3.1 It can supply ally with power
3.2 Allow telepathy between contractors.
3.3 Given an overwhelming sense of confidence

Marquis Voban(Shiniki no Campionees)
After the end of devil kings civil war, his soul was stabbed by Lancelot, but he's still survive and wander aimlessly into the world of the second series. He performed a resurrection ritual which take several year to succeed, but he accomplished it and return with an appearance of a young man.

While he lost some of his authorities after his "death". Although, he gains 2 authorities from Fenrir and heretic god Gordius

1. Ragnarok wolf(Fenrir):
1.1 It will summon 60 meter wolf skull that can swallow the sun due to Fenrir's legend.(I start to think that this guy really have some grudges against sun deity.)
1.2 It can create a crater of a few hundred meters in diameter, and it's destructive force is extremely hard to stop.

This authority is hard to control.

2. Unnamed authority(Gordias)
1.1 It boasts a power to "cut the fate"
1.2 It allows user to defeat a country that's not suppose to be defeat and kill immortal gods and demon.
1.3 If use this authority in a form of dagger, Voban can cut a restrain that's not suppose to be cut. He uses this authority to cut Fenrir's restrain.
1.4 This authority can counter causality manipulation authority.

Soul of the spell book(I rename it a little bit)
1.1 this is an evolved form of Voban's singing spellbook. It's original appearance is that of a magical tome at a size of 10 years old kid.
1.2 Voban doesn't want to flip the pages, so it improves its usage by turning into an appearance of 12 years old girl with purple dress.
1.3 It can use magic that suits Voban's need. It can utilize many high-level spells(Instantaneous teleportation).
1.4 It can inform Voban of the mythology and information of the area that he desire.
