Anime Vanguards (AV): How to get Investigation Leader (Truth)

The searches for “how to use investigation leader” land on a unit, not an item. Investigation Leader (Truth) is a Mythic the wiki dates to 10 August 2026, in the 25th Hour (14.5) update. The design note on the page points at Yu Narukami. I am not copying a biography from another series. The rank I can cite is on the 23 Sep 2026 tier list: inside the DPS sixteen and the support sixteen. It is not in the overall top 8.

Obtainment I can quote

The unit page's obtain panel names Arcana Daily Rewards day 1 and Lunar Bridge Dungeon floor 1 (20 percent, pity 7). These are source-listed routes, not proof that a historical daily reward remains claimable today. The evolution item costs 200 Controller Tokens at the Lunar Bridge Dungeon shop.

How to use the unit

Truth is a Spark Mythic. Its passive restores nearby units' meters and gains damage when MP is consumed. Trenchcoat Demon Familiar strengthens the unit and Demon Controller allies. Demon Controller selects a familiar attack. Rest pauses attacking to build a damage buff (up to 100%); resume attacking to use it. Myriad Truths is a once-per-match-per-player attack, so reserve it for a threatening wave rather than assuming it resets on a short cooldown.

If you are farming the dungeon, the related mode notes are on modes. Pity for banners is a different counter and is explained on secret units and pity.
