[PriConne] Summon for Valentine Shizuru

Valentine Shizuru is a CB support. She is a must for CB players. Valentine Shizuru isn't as delicate as Xmas Chika. Valentine Shizuru will live for long as 12-5 (no middle left) while 9-3 (top left, top right & bottom right) will be used on rare occasions. Bond wise, normal Shizuru will give toughness while Valentine Shizuru will give offense. For CB hardcore, you might consider not getting the stat bonus from the normal bond. But for PVP, the normal bond is a tremendous aid.
